I'm not what you would call a fan of Donald Trump. I think his mouth outpaces his brain by about four lengths, and he speaks in sound bites and pep-rally jargon rather than gives specifics. Marco Rubio [sigh] would have made a much better candidate, and a much more formidable opponent than Trump would be, if polls are to be believed.
That said, I don't believe the lunacy at Trump rallies is all his fault. DJT's events are being disrupted by activists with the same sort of tactics seen at college campuses, where students and their aging mentors simultaneously cry out for free speech and chant to drown out any speaker they don't like. Consider what Milo Yiannopolous and Ben Shapiro have had to contend with in the last few weeks.
"Free speech for me, but not for me," as Nat Hentoff put it.
It's one thing to stand outside a Trump rally with a sign in silent protest; it's another to cause a disruption at an event. This is not to comment on how such disruptions are handled, except to point out that any protestor who displays violence should expect the right of self-defense to be availed.
I'd rather have any other Republican as president than Donald Trump, but I don't want harm to come to him.
