I've sen a lot of angst over the last week about people on the left expressing approval for 'punching nazis' following Richard Spencer suffering a whack on the ear during a TV interview. It's true, someone, probably form the left, carried out an act of physical violence while he was just standing there talking.
But let's not forget that Spencer and various members of his social circle have - for years now - been expressing approval for ethnic cleansing and even straight-up genocide. Some people say that the solution to objectionable speech is more speech, but that's an easy stand to take when you're not one of the people who should be 'ovened' in alt-right parlance. Oh sure, they're just expressing their dislike and probably don't have an actual to plan to construct ovens and shove people into them, but this is not the sort of joke whose punchline I care to passively wait around for.
When people are promoting genocidal ideas and attempting to normalize them as political discourse, they are themselves engaged in political violence, notwithstanding that it's indirect incitement rather than active commission. If you've ever been the target of gang violence than you may have experienced the phenomenon of a smart person calling the shots, while bigger and less cerebral types do the actual punching and kicking. That's why, if you find yourself cornered by a gang, you should focus your attentions on the guy at the back rather than the toughs in the front.
It's true that not everyone who voted for Trump is a bigot. But they were OK with voting for one, weren't they? The longer someone makes excuses for this sort of thing, the more responsibility one takes on for it. You say you're worried about the rhetoric from the left, but it's Trump who has been going about expressing a desire to use nuclear weapons, punish women who have abortions, muzzle the press, demean women and so on.
I am absolutely not going to apologize for being against such statements or moderate my condemnation of them. If you let those things slide by saying 'it's just Trump being Trump' or whatever, then you're making excuses for the systematic intimidation of large social groups. Why would you want to normalize such behavior? Why does open opposition to that bother you?
