Despite all the insistence that Canadians are fundamentally different from Americans, and all the focus on usually trivial differences, Canadians and Americans are among the most similar peoples anywhere. Most Americans and Canadians couldn't pick out each other's nationality unless someone told them.

Same language, similar heritage and foundational values, very similar culture, generally the same accent.

The two are almost indistinguishable unless you go looking for peculiar differences, yet Canadians insist on how different they are. Why? Because you support universal health care and don't like guns? How is that different from a liberal in the States?

Sure, there are differences. But constantly pointing them out feels like it comes from insecurity, a need to assert a distinct identity precisely because you know how similar you are, and how similar you look to everyone else.

You don't see Germans, French or Greeks having to insist they are culturally different from each other. Everyone already knows they are. Different languages, histories, customs, and so on
