As a Canadian, I very much understand that this will/can get worse, and not just for the US. The problems of America do not stop at Trump. He is merely the distracting, mercurial figurehead of a dysfunctional government and populist movement.
It is not a matter of friendship --- the average American isn't that different than the average Canadian. Some of my best friends and favoured colleagues are Americans. We can't turn this into Americans v. Canadians. We're all just getting exposed to the same social media cues that feed on fear and despair driven by profit and bad actors which leads to an erosion of trust and goodwill. America may just be a few short years ahead of the rest of us. We need to recognize who/what is driving us apart and fight that.
