How about this?
"This is a pretty diverse group of people, and it's clear that people are going to deal with this election defeat in different ways. Some members are going to come to DU looking for a shoulder to cry on. Others are going to come here looking for a fight. Still others may have completely different feelings entirely. We believe that it is understandible and healthy for people to feel angry or sad or whatever. We do not think it is possible for us to force people to deny their feelings right now, and we're not even going to try (except in the most extreme cases). However, it is clear that certain types of emotions do no mix well on a busy message board like this one. We have decided that the only feasible solution is to enforce a segregation between the people who want a shoulder to cry on, and the people who want an ass to kick.
With this in mind, the two General Discussion forums have been re-named. The "General Discussion: Help and Support" forum is for those people who are looking for help and support. If you feel sad, or if you are the type of person who thinks that we're all in this together, then that is the forum for you. But if you are feeling very angry about the election, or if you are feeling like pointing fingers and placing blame, you should post in the other GD forum, the "General Discussion: Fighting and Acrimony" forum."
