I'm on the record here defending /r/The_Donald. I'm even on the record saying I didn't think it should be quarantined and that I don't think it should be banned in the future. It takes a lot for me to wonder if something actually should be censored. I certainly wouldn't have been on the side of censoring Howard Stern.

Radicalizing terrorists to such an extent that they actually go through with it -- multiple times -- is extreme enough to make me wonder.

The El Paso shooter's manifesto was posted on 8chan for a reason. The manifesto was written specifically for other potential shooters. It contains tips and advice. It explains the shooter's choice of gear and that he needed to use heat-resistant gloves because one of the guns he used was prone to overheating if fired rapidly. It encourages potential shooters to avoid heavily guarded areas and to avoid engaging with security personnel regardless of how confident they are.

Throughout 8chan, I saw many posts subscribing to the general theory that racial violence has been accepted throughout most of human history and the only people who disapprove constitute a tiny little blip on the grand tapestry. The whole point of this ideology was to encourage people to commit acts of violence by indoctrinating them into the belief system that all their ancestors would not only have approved but would have done it themselves.
