What are some good checkmate arguments against religion?

[MindForgedManacle]

Name a logically sound ontological argument.

You should read more carefully. I said there are, so far as I can tell, logical proofs of God's existence. What I mean is that the arguments in question are valid, i.e the conclusion follows from the premises. I don't think the actual premises are true/sound, otherwise I wouldn't be an atheist/naturalist. And to be honest, the least we should be surprised by is logical validity. After all, the following, is logically valid:

All men men are bald;
MindForgedManacle is a man;
Therefore MindForgedManacle is bald.

But we clearly known the argument is unsound.

Now, logically valid ontological arguments would include:

Plantinga's modal ontological argument, the higher-order ontological argument, the mereological ontological argument and (I think) Anselm's ontological argument.

But as I say, I contest each of those.
