I've touched on this in another comment, in another thread - if we are going to assume that people have the right to say whatever the hell they want, how do you reconcile that with the rights of a mob to pigpile someone for speaking their mind?
The short answer is: "You can't."
The long answer is: "You can't, because when two groups are in such a conflict, you either explicitly censor one, or implicitly censor the other."
You can make the same sort of point without such language. Rather than asserting that "everyone who beleives X also believes Y and that is contradictory", you should assert "believing X and Y together is contradictory".
In this case the accusation is that the accused used completely anonymous means to harass the accuser. How the accuser knows that the accused is responsible is not stated.
The problems here seem obvious.
Maybe it's something of a reaction to these frustrations that some progressive circles have adopted this knee-jerk zero tolerance stance, where no crime or perceived crime is too small to attempt to silence someone for. YouTube film commentator Lindsay Ellis went through a bunch of this recently, and basically dealt with it by making a 1.5 hour video where she itemizes everything she's been accused of, and drinks her way through explaining and apologizing for all of it (including, wretchedly, sharing about her own history with a sexual assault).

The problem is how we respond to what we hear. The core casue of the issue is treating online vigilante outrage mobs as an acceptable activity.
Certainly not in the real world. I was very angry yesterday, I wish I could delete that comment
