To be fair, getting of Twitter because you find the interaction became toxic is in line with what he is propagating. If you are a staunch believer in the concept of safe-spaces and trigger-free environments, you would stay on Twitter and expect everyone to adhere to those principles. But the world doesn't work like that, and people become complete and utter twats behind the veil of anonymity afforded by the internet.

If you don't like the way rude people act, and you can't reason with them or have a meaningful dialogue, you can simply ignore them. If a communication tool turns from a cheerful digital village square into a seedy back-alley, getting out of there is sensible. That seems to me opposite of insisting that people accommodate you at all costs, which is what he is criticizing.
