The rhetoric was trolling. It's sad that a childish troll is president but let's call this what it was. Trump trolling Trudeau. Certainly riled everyone up, changed the Canadian elections results, etc. Doesn't seem to matter if it's uneducated masses or educated masses, the intelligence of the masses seems to be a minimum function at best.
But yeah the quality of people in politics is terrible. I thought very highly of Obama in terms of intellect, honesty, pragmatism, etc. Postcard leader. but he seemingly still managed to mess lots of things up. Or maybe we over-estimate the impact this one person on the top actually has on anything.
The rhetoric was backed by action. That is what makes it different than trolling
Not to mention Trudeau has been gone for a while now, so I dont know how that is relavent.
