A ToS which the tweets people are complaining that Twitter didn't ban Trump for did not violate. I mean, it should be obvious why Twitter doesn't consider support for war to violate the ToS clause on violence - otherwise, every publication which ran an op-ed supporting military intervention and linked it on Twitter would be violating the ToS. Not only that, there was a huge overlap between the people calling for Trump to be banned and the pro-nazi-punching (and pro-punching-anyone-who-wasn't-pro-nazi-punching) crowd who had been taking full advantage of the laxity of Twitter's "violence" clause in the ToS.
There underlying logic of the demands made no sense at all, but it didn't matter. Believing Trump had violated the Twitter ToS and should be banned was simply something you did if you weren't an evil Nazi Trump supporter.
