> A white supremacist killed someone at the weekend for protesting.
Well, yeah, there's been an awful lot of death and injury at protests of late. Charlottesville is easily the worst, but isn't where it started, and it's not where it's going to finish. There were thugs at UC Berkeley smashing property, lighting bonfires, and putting pepper spray in protestors' faces.
Now, I wouldn't want to bring that up first thing like I'm some sort of spineless "both sides!!" equivocator (coughdonaldtrump) after some fucking Nazi runs people down, because it's obviously materially worse than any previous incident to date. But hey, if you we want to articulate a policy of ad-hoc censorship of speech because it reduces the free space to express opinions, let's go there! Why aren't you calling for content providers to root and and destroy all the publications telling us that "speech is violence" and should be met with violence? Where's the pressure for Reddit to drop /r/antifa? Can I get a statement condemning the shenanigans at Evergreen State College, where a professor got death threats for saying he was uncomfortable with a proposed "Day of Absence" which would see him excluded from the campus on account of the colour of his skin? Can we see Huffington Post's cloud service suspended for defending the student protestors who did so?
I can't say I like Berkeley's leftist thugs much more than I like Charlottesville's Nazis, but I'm damn uncomfortable with censorship that targets either. (And yes, it's censorship, even if it's not government censorship.)
But yea, you're right about one thing, it's a sucky time all around if you care about free speech.
> You can't use a civilised person's inevitable experience of "well, I didn't want to cause offense" to justify Nazis.
Well no, you don't justify Nazis period. You use them as the legal equivalent of a meat shield.
> Fundamentalist free speech advocates make an implicit assumption: that a race of billions of social animals can completely avoid situations where one group makes another even feeling uncomfortable.
"Completely avoiding situations where one group makes another feel uncomfortable" sounds more like a conservative caricature of political correctness than any component of fundamentalist free speech advocacy.
