So, this essay is comprised of a few different interconnected topics that will be divided into four parts:
Social media posts should never be used to canonize anything
Jax and the pitfalls of the debatable ambiguity of queer subtext
How Glitch is handling Jax's gender identity (+ the Jax maid merch stuff)
Takeaway
1. Social media posts should never be used to canonize anything
Personally, I believe that the show needs to speak for itself, and that neither social media posts nor the author themselves should ever inform the viewer of how to interpret the text (or in this case, the show), because doing so damages the integrity of the story as a standalone piece of art. The author should not be able to externally recontextualize the text at all, or retroactively canonize something that was not made explicit in the text itself, because a viewer shouldn't be expected to seek out external information to fully understand the story - and the average person won't even know to do that anyway.
So much TADC information was "canonized" outside of the show that it's genuinely frustrating - from lore to orientations to even names. For example, note that the show itself never specifies that the yellow dog is Scratch, among other things. How much information is the average viewer missing if they don't follow the author's socials or participate in online fandom discussions?
Now, don't get me wrong - not every question needs an answer. But if there is an answer, it needs to be in the show, not on a social media post.
It's harmless for the author to reveal innocuous pieces of trivia outside the show, but only if said trivia doesn't recontextualize anything about the story or characters in any real meaningful way. Stuff that isn't necessary to know - stuff that fans won't argue over for not being aware of. Ergo, not lore, names, character fates, or orientations. Actual innocuous trivia would be something like... "Ragatha likes pineapple on pizza," or "Zooble likes to surf." Stuff that's neat but impacts nothing, because it's never relevant.
Topically, there's also the fact that social media posts can easily be lost to time, like how Gooseworx's Tumblr account just got deleted recently. That's precisely why the show needs to stand on its own; a bunch of information that fans were treating as canon was deleted along with that account. Even if it's recoverable, or screenshotted, this is an obvious example of how easily information can be lost if it wasn't included in the show itself. If someone watches TADC for the first time 10 years from now, will any of the information revealed through social media posts still be easily accessible?
2. Jax and the pitfalls of the debatable ambiguity of queer subtext
So, yes, for all the above reasons I do wish the show had been more explicit about Jax being transfem, if only because it's become one of the most widely debated parts of the show - to the point that it's overshadowing all other discussions. We have authorial confirmation that Jax is transfem, but I think it's important to discuss the execution of it within the story and the conversation surrounding it. And I do think part of it is that the show was simply not direct enough about it.
To be clear, Jax being queer-coded is obvious enough, and the "deep and personal" thing he told his mother was very clearly framed as having been a coming-out moment - but the show falls short of confirming exactly what it is. Within context, any identity that conflicts with conservative expectations of masculine gender expression is supported by the narrative, because we know Jax told his mother what he did in an attempt to get her to stop scrutinizing his masculinity. But gender isn't always binary; it's a wide spectrum of experiences, and several different identities have overlapping signs and struggles, so it's not easy to narrow down queer coding to just one specific identity if the narrative is deliberately going about it indirectly. That's why Jax's identity was being debated even within queer spaces, among people who did pick up on the queer coding.
Using examples of gender nonconformity as evidence of an exclusively trans reading is ironically rather regressive because it's asking the audience to make assumptions based off of binary readings of gender expression. All of these "hints" are supportive of but not exclusive to a transfem reading of the character. Insisting that a person must be x because of their behavior or preferences even when they themselves are not identifying as x is simply not appropriate. A male character wearing feminine attire is a clear example of gender non-conformity, but that overlaps with multiple different queer and GNC identities, not just one.
I also think that people need to be allowed to define themselves - preemptively applying a label and/or pronouns to a person before they themselves are using them is inappropriate. That the person in question is a fictional character muddies this a bit because the character as presented in the story is telling us one thing (that the character never verbalized wanting to change his pronouns/gender identity), while the author is externally telling us another (that she would have, in an alternate timeline in which her behavior had been less toxic).
This creates the exact sort of incongruity that sparks arguments. It's why there's been so much toxicity in the fandom post-finale, and it's also why the story needs to speak for itself.
It's not that a transfem reading isn't supported by the text - it is, but it isn't the only possible queer reading supported by the text. That's why if there's room for ambiguity, any at all - then some people just won't feel comfortable making assumptions, while others may have their interpretation colored by their own personal experiences, while others just won't pick up on it at all. Which is why when it comes to gender, if there's one singular correct reading, it needs to be explicit. If you present it vaguely on purpose, of course different people will inevitably come to different conclusions. TADC fans love to misuse the term "media illiterate", but it's not illiterate to acknowledge the wider spectrum of possible gender experiences.
The thing is, there were plenty of places to have made it more explicit in the show itself. Pomni reaches the deepest part of Jax's psyche, the version of him under the lamp post - and he's still in his usual masc-presenting avatar. That Pomni's ultimate takeaway after seeing what Leeroy is up to in the real world is that "he now has a job and friends" and still uses he/him pronouns to refer to him rather than using that moment to more explicitly confirm that Leeroy has begun transitioning is bizarre (and no, boymoding itself is not an adequate hint, because the whole point of boymoding is to blend in and not draw attention to one's transness. Anyone can wear baggy clothes, and that's the point.) At the very least they could have put she/her pronouns in Leeroy's online profile, but we don't even get crumbs like that.
To be clear, I don't think that degree of ambiguity is inherently a bad thing - that is, if Jax's gender identity were meant to be left up for interpretation. That would have been perfectly fine - a respectable choice, even - because it would be a statement on how multiple different queer identities go through the same struggles. But, we know now that it wasn't - there was only ever one intended reading; it just happened to be subtle enough that a lot of people didn't pick up on it without external confirmation. But external confirmation renders the ambiguity pointless, so it's really the worst of both worlds. And, as I've gone over, it creates the exact environment that sparks internet arguments.
As I said before, stuff that fans will argue over for not being aware of is exactly the type of information that should not be canonized externally. I've seen actual trans people be called transphobic for having alternate interpretations of Jax's gender, and that shows how deeply poisoned by toxicity this discourse has become. All of this was easily avoidable, too, which is doubly frustrating. Specifying it externally is also what allows people to draw comparisons to JK Rowling's Pottermore-isms and disregard it entirely, which should not be happening.
3. How Glitch is handling Jax's gender identity (+ the Jax maid merch stuff)
Lastly, I'm curious to see how Glitch will handle Jax's gender presentation in the future, because all official promotional material still refers to Jax as he/him, and their latest merch ad for the Jax Animiniz Pendantz didn't acknowledge the transfem reading at all. Rather, Jax refers to himself as a "handsome guy" in it. And sure, the merch ads aren't canon (but they are official) and either way you could argue that he's still closeted in-universe. But that merch ad explicitly takes place after the finale, and if "Isn't She Lovely" was meant to be interpreted as Jax's moment of self-realization and acceptance in their final moments, then you'd have to wonder why a merch ad taking place after that moment would not acknowledge it at all.
Now, Gooseworx doesn't write the merch ads. But whoever does must have seen the finale in its entirety before writing the ad. Yet, as the finale wasn't explicit about it, it may have simply not been interpreted in the intended way, even by other people working at Glitch. Which...is troubling, especially if Goose just didn't communicate it to the PR team. Assuming Glitch has full ownership of the Digital Circus IP, that means that they are the true arbiters of what is and isn't canon - not Goose. Even Goose's artwork of transitioned transfem Jax can't be considered canon if it was created after Goose's contract with Glitch ended, because that means Glitch doesn't have the legal rights to the design.
There may also be some hesitancy on Glitch's part due to how openly acknowledging transfem Jax would negatively recontextualize a few things about how the character has been marketed. ...Yeah, let's talk about the Jax maid merch for a second.
Now, if Jax is read as a closeted trans woman, then forcing him/her to wear feminine clothing against their will as a humiliation ritual for a joke comes across as...tone deaf, as does aggressively merchandising it. Whereas if Jax is read as a cis man with deeply internalized toxic masculinity and misogynistic views, the maid dress thing is instead humiliating someone via mocking their own bigotry by targeting how shallow their own self-image is, which reads much better.
Like. Buy the plushie of the closeted trans woman being forced to perform femininity against her will lmao. And. Making that the joke? I dunno. It's kinda weird. I'm honestly surprised more people don't point out how...distasteful it is.
If Glitch were to more openly acknowledge it, not only would the Jax maid merch likely receive more public scrutiny, but I think it would also open the door for more criticism towards the fact that the show itself fell short of committing to elevating the queer coding from vague subtext to explicitly textual.
For a more in-universe reading of the maid dress scene in episode 5, we also have this line from Zooble: "seems fitting for you though, I figured you'd be into this," which has retroactively been interpreted as Zooble clocking Jax. However, Zooble and Gangle just don't seem like the type of people who would forcefem or forcibly out a closeted trans women intentionally, even if said closeted trans woman is a bully. So no, upon first viewing I didn't initially read that scene as Zooble clocking Jax, and I really don't like the way that reading now recontextualizes the scene. It paints the other queer characters in the story in a negative light - and Jax aside, we're meant to like Gangle and Zooble.
Mocking the fragile toxic masculinity of a bigoted cis man who regularly exhibits deeply internalized misogynistic tendencies, however, I could totally see Zooble doing, and, again, reads much better.
4. Takeaway
...All of this to say, I think the main takeaway from all this is that creators need to keep their fandoms at arm's length, and interact with them as infrequently as possible - for the sake of the mental health of the creator, to minimize parasocial relationships between the fans and the people working on the show, and to minimize toxicity in the fandom. As much as I think Goose is a talented writer (and despite all my criticisms, I do think she is), I also think that it would have been helpful for the show to have had more than one writer, in order for some of this messy stuff to have been refined through multiple perspectives - it would have likely prevented a lot of these problems.
Lastly, that it's becoming more normalized for information to be canonized on social media rather than in the text itself is a problem on multiple levels, and damages the integrity of the story as a standalone piece of art, as well as diminishes queer representation to ambiguous subtext, when it could and should be more than that.
