"Does God"
No. Do not go any further. There is no God, therefore he does not do anything.
"use the so called 'atheists'"
Please do not refer to me as "so called." You may think my opinions to be wrong, but they are my opinions. I don't call you a so called Christian. I think your beliefs are stupid, buttheaded, inane and ridiculous, but I do understand that you actually believe that rubbish.
"to make Christianity look superior?"
Nothing in the reason and logic of atheism makes Christianity makes look superior to it.
"All things end up serving God, whether they intend to or not."
If that's true, why do you whinge on about having to end abortion, fight Satan and stop atheists?
"The so called 'atheists'"
There you go again.
"on R&S make themselves look very childish in both their questions and responses, thereby discrediting the same thing they intend to defend or believe, and making Christianity look better by default."
Yes, but then, childish responses are found on the pro-Christian side too.
"Is this God's ironic symmetry at work?"
No. Remember, God is just an imaginary being. He does really exist and he doesn't really do anything.
