Satire for Sanity
As such, a website could justifiably take those down arguing they don't want the potential lawsuit. That's reasonable. Any post that could be legally actionable by a party reading it could be removed. Removing them wholesale on the other hand, is wrong. Removal should be the exception, not the rule. All of your examples, except the one from the Senator, would be actionable and cause for removal. The Senator's is public speech and war is different from advocating murder or genocide. War is a political thing.
So we're already into the realms of the absurd- if somebody can be prosecuted or banned for denying that six million people died whereas it's acceptable for somebody else to actually call for the deaths of hundreds of millions of others.
