These protests are frustration and nothing more. Had Clinton won, the streets would be full of his supporters heavily armed and more belligerent.  The possible right-wing  response to Clinton winning the election scared me more than Trump just winning.

Protest like these happen all the time and results are usually minimal with some inconviences

I say this because I lived through the riots of the 60's against racism and Vietnam. Trumpism has not come close to raising the hackles of Americans like that, but it very well could depending on how he presides.  He is politically ignorant enough to commit an impeachable offense within his first hundred days.  I don't think he can make it through a term without saying or doing something really bad.

Until Americans really gets upset, they will just protest. Large riots raise the stakes dramatically. I is their right and really not worth criticizing at this point.
