Look, bottom line is, Trump has only said the things he's said because of people deliberately trying to disrupt his rallys. Again, I don't agree with what he's said (admittedly stupid and immature), but had these people not turned up to cause trouble then none of this would have happened quite simply. I really don't see how anyone can argue that. Personally I think Trump has Been provoked into this situation.
You can't go along to someone's presidential rally intent on causing trouble and not expect to receive angry backlash. Then to cry about it afterwards claiming you have been treated unfairly or whatever, kinda pathetic.
And lastly, no Trump supporters have turned up at any other candidates rally to try and cause disruption, as far as I'm aware. That in itself tells you something.
