It's not misuse if it's common usage, it's simply usage you disagree with. Obviously when people say "Nazi" they don't mean "members of a 1930s political party," they're making a statement about something else. If you find the usage of these words confusing that's on you, not the words or the people using them.
> Have you no concern for possible second order effects of poorly thought out and biased censorship?
Not particularly: if those things happen, let's protest those instead of wringing our hands and worrying about the poor slippery slope.
> And when I say censorship, I'm not referring to the First Amendment.
Deplatforming is not censorship. You are not guaranteed an audience for your speech. White nationalists can still say whatever they want, and they can even say it legally. But they can't say it on Facebook, and it's not Facebook's responsibility to let them any more than it is to let pro-ISIS people post their content.
> If the incidents are the problem, why is the enforcement (and news coverage) racially biased?
This is irrelevant to the discussion at best and disingenuous at worst. Facebook can ban multiple kinds of content, including pro-ISIS content (and it does). White nationalism being banned is what we're discussing here.
> How sure are you that these incidents are caused by incitement on social media?
I believe that social media is helping incite these incidents, so I do legitimately believe the amount of people participating in hate crimes will be reduced as a result of this. Do you really think that people aren't radicalized by communities on the Internet? Communities that might exist on Facebook?
Of course, I also think it doesn't matter if that's true or not. No discourse of value is being lost by banning white nationalism, and Facebook already bans a plethora of other (totally legal) content because they don't think is appropriate on their platform. If you want to read white nationalist speech, it still exists. This merely means you can't read it on Facebook anymore. How this is a tragedy I simply cannot understand.
> Is that so, or might that only be what you presumed or were told?
Yes, it's so. Read the manifesto.
> Is this worth considering when setting policy?
No. People can (and will) do anything in response to anything; maybe white nationalist groups will make Zuck their #1 enemy over this. You can't control the actions of other people, especially crazy people, so catering your policies to them seems absurd.
> For the sake of improving the quality of discourse, can you sense any legitimate concerns in what I'm saying, or do I seem to you like yet another ignorant racist, little different than those who might frequent Charlottesville rallies?
I don't really see many legitimate concerns arising from banning white nationalism from Facebook. As I've said multiple times, Facebook already bans other kinds of speech they disagree with. I get defending free speech is a thing, but Facebook is not the government and they can ban whatever speech they like. They don't control the entire Internet or even a majority of it, and they can't prevent you from hosting your content somewhere else, so... I just don't see what's being lost here, except white nationalist content on Facebook.
And even if they do go ahead and decide to ban other content, I mean, A) let's cross that bridge if we come to it and B) who cares? It's just Facebook, they don't control the entire Internet. Make another site if you want to discuss what they deplatform.
