The president continually belittles Canada calling it the 51st state. Would you be happy if another country's chief officer continually demeaned and belittled your nation?
It's not who he is but what he says about other nations. Of course, Canadians won't be happy with America right now.
Also, politics have real life consequences to people. When someone you love has their health and well being threatened by politics, yeah, there are real emotions. And that's all I'll say on that lest things get too heated.
