Have you ever seen this one?
"Atheists have no beliefs about God! In fact atheism is entirely about the LACK of certain beliefs! That's it!"
And then immediately, by the same person, maybe even the next sentence...
"Atheists believe in the importance of (insert various moral / ethical / laudatory traits here)!"
A related move is this: "Being an atheist doesn't mean you can't be moral! You can value honesty! Or compassion!"
Which leads me to ask, "Can you value killing hookers and making a parka out of their skin? Is that compatible with atheism too?"
I imagine that works better if you're wearing an apron and a hockey mask at the time.
