I think the bullying aspects of the responses run both ways. Sometimes believers gang up on atheists in here, too. But we are talking about precious world views here and people often want to defend their views even if the "offending" comment isn't directed at them specifically. I do think people should be able to raise objections to points made by others if they are public and then discuss them, even if they are about atheism or religion. The problem is that people sometimes raise such points and have no intention of listening to answers they get. That's when it becomes a waste of time. It's one of the reasons I tend to bow out of debates early on unless they are very civil. For me, it just isn't worth the frustration, and debating isn't why I joined JWD. I've done enough of that in other forums.
Note that we atheists sometimes harbor a fair amount of frustration over supernatural/religious issues that are generally accepted by others. It seems, to us, that people often want us to just shut our fat gobs when they are speaking as if we have nothing of value to offer. This encourages us to do the opposite just to maintain the right, so we can be quick to pounce on certain posts when we see them. Sometimes too quick. The fact that we are often misunderstood doesn't help, either. Some of these posts may seem innocent to believers, but are screaming for a reply when read by atheists who go "WTF!?!" as soon as we see them. Just as some atheist posts seem innocent to other nonbelievers, but are pounced on by deeply religious members of the board.
BTW, I wasn't always sure about Wanderer's intentions either. I used to think he was trolling as well some of the time. But I don't think that any more. He just likes to ask provocative questions, though he always seems to present them from a believer's point of view. He phrases the questions in a way that we atheists often find antagonizing. I don't know if he means to do that or not, but I don't think he means to troll.
Peace out, Wanderer!
