The Fascistic Leftist pro-censorship crowd isn't even trying to legitimize their actions anymore.

First there's the 8chan situation: actual killer uploads "manifesto" to Instagram. Someone else re-posts it on 8chan. 8chan gets taken down, Instagram does not. And about 8chan as a site, it had a wide range of political discourse on it, as explained perfectly here, not just right-wing stuff.

Second there is Mitch McConnell: the "just stab the motherfucker in the heart" #MassacreMitch posters do not get banned. Mitch McConnell does for pointing out the "hashtag".

Third there is the Gab scenario: radical Muslims, Antifa, BLM, and other Leftist radicals routinely user Twitter as a platform to coordinate. But, Amazon pulls the plug from Gab, which had quite literally nothing to do with either shooting.
