I want to parse this out, not actually because I'm mad or annoyed, but because we exist on different sides of a chasm and it's interesting to see others perspectives.
The old adage of when the US sneezes the World gets a cold is particularly true to Canada. For better or worse we are not citizens, but what the US does matters a heck of a lot to us.
I think what irritates Canadians is having the US apply their beliefs against our society. What the US finds controversial topics are sort of settled issues in Canada. Universal Healthcare carries 90% support for example. Does anything in the US carry this level of support? That's sort of rhetorical, but those things are closed issues.
Continuing the example, Universal Healthcare is really not a viable debate, but of course is an extremely hot topic in the US. Vaccine passports carry near equally wide support. A lot of the noise is from a loud vocal minority of Canadians or a much larger ?minority or maybe even majority of Americans. I have no problem with people speaking their stance, but it's worth pointing the stance is not applicable to the sentiment up here.
Generally the majority (in Canada) still feel we are not doing enough. So pointing out what is happening in Canada is not a justification for the US to do less, it reinforces the belief that we still generally want to do more. Some will and have no doubt left, but most do not want to.
