As stated prior, no one pushed or shoved their way into "private" rallies. They bought tickets to Trump's event(s), essentially earning them their right to protest within the establishment, since they paid their dues. They absolutely didn't use violence to get in their. They used earnings, and that's called Capitalism.
Once again, if anyone is pushing, shoving, sucker punching, making idle threats, and even death threats, it's always been Trump's supporters who have said and done these things at his rallies.
And as far as Trump supporting Hillary up until last Spring (Yes, that's true too. He donated to her until then), I'm not a conspiracy theorist, but I think two evil people are working together (Trump and Hillary) to make for one of the most ridiculous elections in American history. So far, they are doing it. The most unqualified candidate from both sides of the coin are going to represent their party and one of them will become president.
If that's the case, you're voting for the lesser of two evils, which is like drinking the slightly less poison that's going to kill you.
