For all the people downvoting, it's true:
https://twitter.com/hashtag/killallmen
About half of the tweets are serious "killallmen" comments. The other half are people complaining about it. And, complaining that twitter won't do anything, despite their terms of service saying such behavior is ban-worthy.
Or look at twitter banning Milo... because other people engaged in harassment. People who had no clear tie to Milo.
At no point could Twitter point to Milo's behavior, and say "this violated our terms of service, so he's banned". They just banned him, despite their terms of service.
I've mentioned this before on HN, and asked "What, exactly, did Milo do? Please point to something he did."
I received no replies, but got plenty of downvotes. Which says to me that the people involved (like the ones downvoting here) know their opinions are contrary to all facts and reason.
So if you're thinking of downvoting, try instead to convince me I'm wrong. Adult discussions are much more productive than naive attempts at censorship.
