I don't know. I'm a pretty prominent DUer over there, and tend to get them going on a lot of their more prominent threads (let's just say You know my work) but it's so troubling to post some crazy Dean-loving thread and see all the wackos hop all over it. I've worked in volunteer work with young people (non-religious, left-leaning charitable organizations which are the only ones servicing the area I work), and I can say that if someone wanted to volunteer and had the attitudes these "humanist DUers" have, I'd toss them on the street. So that's why I'm considering not hanging there so much anymore.
How you stuck around long enough to get to that level, without barfing so much you're bulimic, I'll never know. I posted stuff I knew would get a rise out of them, but it was hard after a while even stomaching some of the return posts I'd get.
