It's easy enough to stay out of such threads, and I generally do these days. But I wish that there was a way of avoiding that kind of stuff, which gets in the way of real discussion, however heated that might be.
Cutting out the ability of GUESTS to start threads at all would of course be one way. And recently enough it looked as if that was what Max had determined should happen. But there are drawbacks to that - and in any case you don't have to be a GUEST to do that kind of thing.
So how about this for a suggestion? If someone opens up what is clearly tailored to be a hate-thread, but it's about something you want to discuss, don't respond in that thread, open up a new thread on the same topic instead. (And it's what happens already sometimes of course. We are learning how to avoid the traps set for us by trolls.)
