I don't know if you've noticed, but Hacker News is not exactly terribly popular amongst the social justice part of the tech community. Also, users' opinions can only be influenced by threats of violence that they hear about, very few people who aren't in the immediate social circles of the offenders generally hear about these threats, and those are under social pressure to accept them for obvious reasons. Not banning people who haven't made threats of violence but whose opponents have tried to tie to unrelated people that have for political reasons has probably done far more damage to Twitter's acceptance amongst people who refuse to participate in communities where death threats are normal.
