I've heard that he's been doxxed and people are trying to get him expelled from the DSA?
As far as I can tell, it's for trying to dunk on someone with this tweet.
Is he in the wrong in some way I can't see, a victim of overreaction, or do I just not have the full picture?
Not everyone is going to ever "delete Twitter" so you definitely should NOT delete Twitter and leave it to become a feedback loop of anti-communism fueled by wreckers. Refute arguments but don't do petty stuff.
