Is there a reason CalD's GD thread is still going on?

If by troll, you mean someone that has done this topic before (religion and God) and pretty much in this same format, then I’d have to agree. CalD has started several threads since 2005 with the same theme that went the same way.
If by troll, you mean someone that doesn’t believe what they’re saying, I’d probably disagree since I don’t know what he’s thinking.

Cite.
If you were going to cite this:

don’t bother. That’s not what it says.

To the OP: I’ve only read two pages of the linked thread, but so far, the people trying to do the convincing that an intelligent designer doesn’t exist are making a pretty poor showing.

While I’ve only read two pages of the thread, the GD participants don’t seem to be doing much of anything that’s convincing so far. I’ll read more and see if I understand what you mean.
