In this case the answer is very simple - use different drugs. The simple fact is that 9/11 is a dead issue. Pretty much everything about it has been discussed to death, and the only people left here who deny reality are either trolls, sock puppets or mentally unstable. No matter what your reasons are for coming here, there is no reason to do so any more, since every new questions is just a repeat of an old one, occasionally trying to disguise itself as something else.
However, the point, that has been mentioned many times before, is that this is not the only section of the forum, and there is absolutely no reason to behave as if it is. If it's the sense of community you want, there's the community section. If you want to discuss other conspiracies, there's the conspiracy section. If you're interested in general skepticism and debunking, there's the general skepticism and debunking section. And so on. I think there are very few people here who are only interested in 9/11. For those few maybe there is nothing left here, and they should probably call it a day and get on with their lives. However, for everyone else there is still plenty to do, whether it involves skepticism and debunking, general arguments or just being part of the community.
The bizarre truther vs. JREF fued may have been amusing at the start, but beating dead horses can only keep you entertained for so long. If anyone still wants to see a horse being beaten, there are plenty of threads and links around here to show them how, there's really no need to continue beating the poor thing.
