If someone is threatening to commit violence, there are already perfectly effective legal ways of dealing with it. If anything, if you do deplatform them , noticing that speech becomes significantly harder, while they become more radicalized (and if Zuckerberg did not exist, anti-semites would have had to invent him; but he does exist).

To go back to the original article, though, it is interesting that they are banning white nationalist content. Does it mean that any other nationalist content is just fine. And can I start an Even[0] separatist movement on FB, calling for eradication of the whitey? We'll start with Russians, of course, but after them we're coming for you! /s

If I didn't have better things to do, a conspiracy theory of FB (they did elect Trump, as everybody clearly knows) being in cahoots with Stormfront and specifically calling out whites to stir resentment almost writes itself here.
