Oh, good grief. You are accepting almost the same narrative that was foisted upon the Tea Party when the big Tea Party rallies began occurring. The Tea Partiers are racist. They are homophobes. They want to re-enslave blacks. They are ANGRY. Who knows what they might do...
Of course anyone who went to a Tea Party rally knew the attendees were 99.9% nice, respectable people who behaved well and cleaned up after themselves. They were angry about what was happening to their country, and rightly so, but not in the sense of violent intent. Nor were they racist: My wife is a quite “brown” Asian-Hispanic with a strong accent, and no one was anything but totally polite and nice to her.
Anyone who thinks that some of these protesters are not going to Trump rallies looking to physically disrupt them is dreaming. Any one who thinks that if Cruz was well in the lead, drawing big crowds, and convincing a lot of people that he will do what they have been clamoring for, and would not have tumult like last night occur, is similarly dreaming. This is how these people (the far left) operate, when they think they might not get their way.
And the people we are trying to get rid of are exactly the same ones who give in to them; that's why we're trying to get rid of them.
The fallout will be increased pressure against concealed carry and hand gun ownership.
