Just a suggestion, which I'm not sure would be workable. When a thread turns sour, what about privately locking the offenders out of just that thread? Cooler heads could continue the discussion, and maybe after a couple of such banishments, the hotter rhetoric would subside. We'd also not permanently lose the posters from the forum. Despite the heat of some discussions, they still offer insights I value.

Mind you, I'd be immediately locked out of any thread praising Anne Geddes...
