I did another quick read through and I didn't see any screaming match that involved Dave. I did see one on a sub topic that didn't involve Dave, but none of those were banned.
Ad-hominem attacks are not unique at all. Many posters routinely attack the motives of other posters and never get banned. Check any evolutionary thread and creationists will routinely claim that those on the evolution side of the debate only feel that way so that they can "justify their immoral acts." If not that, they are accused of hating God and having a black soul.
In this very thread, Dave's endured ad-hominem attacks against his motives - he was accused of wanting to further the leftist gay agenda. He posted links from National Geographic to further his point that homosexuality is not symptom of sexual molestation and he was accused of posting leftist propaganda.
I'm hoping that their is more to this banning that what I've heard from those in this thread. If believing that homosexuality is just a personal choice and not a symptom of some childhood molestation is reason enough to get banned then this place is going to get real empty real fast.
Jeff,I have been following this thread and it might be because he was a retread,was banned before-just guessing.
