I don't give a flying **** how frustrated they were getting -- it doesn't warrant violence. I was at a Hillary rally last year. There were protesters. They were peaceably escorted out and she continued her speech. That's how you deal with protesters. You don't beat them up. Even worse, you don't have candidates encouraging supporters to beat them up.
When a man walks up to another man in a tense situation and says "**** you!", don't act surprised when fists fly. The flipping off of the crowd was the protestor's ...THE PROTESTOR'S invitation to violence. He wanted violence. He was inviting a fight.
Thousands more showing up days later flipping off Trump protestors (and ripping "Trump" signs from their hands) were wanting exactly the same thing...inviting exactly the same thing.. So you don't have the luxury of playing the sweet innocent little crybully.. And BTW when thousands show up to incite violence that's called "Inciting a riot" and it's illegal.
Many of the "protesters" initiated violence when they were asked to leave. I don't recall any of you leftwing hypocrite douche nozzles saying anything about that.
Prove it
OK:
(Protestors flipping off and blocking an ambulance last night)
Such a "peaceful protest"...even after it was called off...
