OK, here is what I am trying to do:
Max 3 political/religious threads. I recommend those with thin-skins to stay out. These threads will be "stickys". Once they reach about 100 posts, or there has been no activity on one of them they will be unstuck and "closed". I will wait a few days and then delete them. I will try to monitor them, if I see one is getting "way" out of hand

I may either put a warning post on the thread, or shut the thread down early as I see fit. If I see that we are "short" a political/religious thread I may solicit for a new one by starting a thread and making it a "sticky" with the title "start new political/religious thread here", I can later modify the title of the thread. If I see a political/religious thread started which would drive the total over 3, I would weigh a few options. I could temporarily allow an extra thread to exist, or if a previously existing thread is slowing up or turning ugly, I may lock the previous thread and sticky the new one. Or I may just delete the extra thread, it's a chance you take if you start a political/religious thread. And I think I mentioned before, when it comes to determining if a thread constitutes a political/religious topic, it's all by my interpretation.
