I didn't see the now-deleted posts, so I can't judge for myself there, unfortunately.
I wonder if [person] had any idea that their advocacy of increased monitoring of this board to purge offensive content, would ultimately help lead to a situation in which open discussion of important issues such as alleged workplace sexual harassment, attempted sex crimes, and the ethics of police tactics, would be censored and/or silenced. To be fair, the possibility probably never crossed his/her mind. And it's the BWW moderators' own choices which are directly at play here. But I think it points to something we should all keep in mind: (teacher voice) if you advocate to silence 'offensive' discussions which you think shouldn't be happening, even with the best of intentions, then sooner or later those same considerations will be used by somebody else to silence discussions which you think should be happening. I think a lot of people (not here as such, but generally speaking) are going to be experiencing rude awakenings about that in the coming years. Anyway, tangent over.
