If it were prohibited speech or if the platform was illegal, this article would not exist and neither would this discussion.
A pretty distinct contrast to the prohibited speech in your examples.
And since we're being impartial, we should just ban entire television channels because they have broadcast these direct calls to violence. Just like 8chan is being de-platformed for a handful of posts that were submitted by users. Right?

Perhaps let's talk about the fact that the individual that precipitated this action also shared his views on twitter and facebook. And they were not removed until he became a figure of media attention. He also used facebook livestream. Time to de-platform those too, yes?
That wasn't my point though, and I'm pretty sure you know that.
