And that argument is fundamentally flawed, and is the point I'm trying to make. While it may apply to other religions, it does not apply to Islam. This is where Dawkins and his ilk show their ignorance and fall flat, and falsifies their entire approach. What appears to them as (or them falsely assuming to be) underpinnings, isn't, if I can put it in another way.

I don't see the parallel to the example you gave. Once you're inside a religion, then you can discuss its details and nuances like the examples you gave. That's a completely orthogonal discussion however. Dawkins and the neo-atheist movement are arguing core basics like the existence of God, then using some fallacies that some religions commit to discredit every religion. See the problem there?
