What are some good checkmate arguments against religion?

[Esquilax]

Something Tracy from the Atheist experience said was quite good, it was on morality and went something like:

If I knew that someone was going to rape someone else, I'd stop them. But your god, simply watches and says to them: 'i'm going to close the door now but once your done, i'm going to punish you'. And that's the difference between me and your god, I would stop someone getting raped.

Not exactly a checkmate argument but I thought it was quite powerful. Of course, its pointless saying that if you're talking to a Christian that believes in divine command theory.

Do you remember how that call ended? Specifically they were talking about children being raped (I listened to that episode fairly recently ) and the theist caller shrugged off the entire issue: "First of all, you're portraying that child as innocent, she's just as evil as the rest of us..."

Which was when he got hung up on before the ensuing Matt Dillahunty rant. The whole exchange is a very powerful demonstration of exactly what's wrong with christianity as a moral worldview.

Just the words :"I now truly believe" that will shut them up and checkmate any Christian.

Since when is conceding the point a checkmate?
