It's been encouraging to see companies grow a backbone and crack down on harassment and hate campaigns, and not hide behind cowardly cries of "free speech." Twitter has taken too much time to do this, but recently they've been doing it more. Even Reddit, notorious for powering and consciously allowing hate campaigns, has cracked down more.
It's also been interesting that the proponents of allowing these campaigns to continue say that stopping them will indeed lead to totalitarian censorship of "free speech."
Granted we must always be vigilant against social pressure going too far. For example, the mob that formed to find the Boston marathon bomber over-zealously targeted the wrong people, risking their lives. We must learn from things like this.
But to jump from banning hate campaigns on private platforms, to total censorship, is an impressively intellectually dishonest juggling act.
