I think at the end of the day there’s a (lower stakes and more online) version of “the cruelty is the point” at work here, whatever you think of that theory. There are certain people who, as a result of trauma or personality disorders or boredom or resentment or some combination of these and other factors, have a strong will to hurt others. They can’t just go torment some random weak, hapless person, because in bien-pensant lefty circles such bullying is in theory verboten. In theory. But if you can find someone who is a bad person (because everyone says they are), then all bets are off: You can bully them and call them a piece of **** and seek to inflict so much harassment on them they flee a social media platform. That’s just social justice, baby! That’s the kind of fearless activism favored by organizations that are “abolitionist, anti-capitalist & anti-imperialist collective amplifying the voice of the people through direct action, public ed + community space.”
