Tell the San Jose Trump protestors that it is illegal to throw physical items at people, attack them with bags of rocks, steal items to destroy.
Trump has at most verbally stood up to hecklers that tried to shut his rallies down and regularly rioted outside the events violently to prevent people from getting in. These same SJW protestors have disrupted conservative speakers and conservative group meetings for years on college campuses, only now hitting the public big events.
The leftist authoritarians are fascists, demanding that others stop speech they don't like or else they'll be violent, because they can't have a rational debate - they label what they don't like hate, don't shut up when countered, they throw tantrums and fists.
When one side of the spectrum says shut up or I'll hit you while threatening to kill your side's leader, it cannot reasonably call itself the side of love and tolerance, though social justice warriors still ironically say such.
