Why do we have two threads on Fred Phelps?
Because Mr. Phelps had an impact upon both U.S. events (largely by causing disgust and the passing of laws to limit where and when he and his followers could emit his virulent hate) and religion (since he claimed that was what motivated him. If he were to be limited to one board, this is probably the best one, since few would agree his hate was religious.
It was a rhetorical question.
Because, as I already said, Fred Phelps was a very effective attention whore.
