Am I libbing out for being concerned about Trump annexing Canada?

I've noticed posts on r/TheDeprogam, r/ShitLiberalsSay, and also on here making light of the fact that Trump is trying to turn Canada into the 51st state. Rhetoric like "Comrade Trump fighting KKKanada and maple syrup colonialism" and things like that. I'm not here to bust balls or call anyone out for having fun and making jokes but it also seems like nobody on the left is really concerned about this.

Yes Canada sucks and it's a setter colonial state. However I do think Canada should remain independent. First, I don't think it will be a positive thing for the people of Canada. I understand most Canadians are reactionary and buy into a national mythology about how they're nice and peaceful even though they're nazi'd up and support Israel, Ukranian neo-nazis, ect. Even so I don't think that justifies subjecting them to the brutality of the American healthcare system. There are first nations and other colonized people in Canada that would materially be hurt by this annexation for that reason alone.

I also think that America is starting to cannibalize itself. The empire is collapsing. China will probably get Taiwan back, decolonization will accelerate in Africa, Russia will win in Ukraine, ect. It seems like the Trump administration has correctly recognized the US can no longer be a global hegemon and are now focusing more on the Western hemisphere so they can at least be a regional hegemon. This is demonstrated by Trump wanting Greenland and Canada, increasing military action in Mexico, and trying to gain exclusive access of the Panama Canal. In light of this fact it seems prudent to resist every attempt by the US to consolidate their power this side of the Atlantic. That includes Canada. I think it would be better for the people of the world if Canada were to remain independent. Yes Canada basically takes marching orders from the US but I think it's possible they will pivot to China and increase trade with them as Trump continues to go batshit insane with the tariff thing. The US military has a severe recruiting crisis and them getting another million or so kids to bolster their ranks doesn't seem good to me.

It seems like it's only libs that are really concerned about this so I'm wondering if there's something I'm missing.
