See, I wouldn't call that slanting exactly. Debate hinges on rules of logic and logic depends on rationality and as you say, the major theistic philosophies aren't often all that rational. But that doesn't mean the argument is slanted... generally it just means that the particular philosophical stance can't be justified through rational/logical means, which is why they call it faith. For better or for worse.
