If you didn't catch Bill Maher's show Real Time on Friday night (February 3, 2012), at the end of his "new rules" segment he had a wonderful "new rule": "Idiots must stop claiming that atheism is a religion". Here is the video:
Perhaps the most insightful part of the video occurs at the 1:22 mark where Bill says:
"Now, it's a dodge, of course, straight out of the grand intellectual tradition of 'I know you are, but what am I?'"
Because it reveals what is almost always true of religious arguments: They are dishonest attempts to dress up reasoning that would be more at home on a kindergarten playground.
