Trump said a lot of horrible shit during and prior to the campaign which you can blame his supporters for implicitly backing. But all of this shit about Canada, Greenland and the Panama Canal only started after the election.
Greenland at least was a thing even in his first term. I'm not sure about the timeline on Panama and Canada, but I also don't see his supporters condemning the rhetoric or even distancing themselves from it.
He spouted every kind of hateful shit, and surrounded himself with even more vile shitstains. Every terrible thing imaginable was put on the table. Some Americans may not have liked the alternative but this election was never about “better” or more tolerable” or any thing else except shortsighted hate.
Reap what you so, this turd sand which does what it said on the tin.
