I especially agree with your final comments. Large pattern abuse is abominable.
But you are not going to change the fact that many human beings don't get along and are horrid to one another. In this group, some will go into territory they would not otherwise go. If the behaviour is isolated, one should try to understand. I suspect a very small number of people are wanton, serial abusers and those people ought to be punished.
Abuse is a terrible thing. But so are lies and spurious allegations. Where there's a pattern of either, you should respond. Where there's no pattern, I think you presume innocence. And where there are incentives, I assume this will influence the behaviour of the parties, and I try to discount it.
Some of the #metoo groupies have told ridiculous stories. And many decent people have been treated terribly: Jim Carrey; Lake Woebegone man; Matt Damon etc.
As you know, my concern from the beginning is that extreme cases would lead to marginal ones, attorneys would enter the bedroom and people would be made to feel bad for merely clumsy behaviour. We got there, and then some.
