I guess in trying to keep a friendly tone to my post I overneutered it. But yes, I was referencing the stuff that was happening in the news article I linked. Similar things happened right after the Brexit vote: All of a sudden, people coming out of the woodwork thinking it's now okay to tell others to "go back to their country" (even natives), to threaten them, beat them up, etc.
The more divisive the vote is, the more violent the winner gets. Bullying is easier when you have the numbers.
America just elected someone who actively encouraged beating people up at rallies. The fallout is going to suck.
