Sorry, maybe I wasn't clear enough. Questioning the existence and using rational arguments for or against the possibility of free will itself is a rational argument that affects theism or atheism. My point wasn't to tell you what my friends believe but to help you understand that there is a whole body of work dedicated to substance dualism that is based in rational arguments. That's just one philosophical subject, there are plenty others. Simply waving your hand and saying that rational arguments about theism or atheism are absurd is lazy at best. Take a look, there are plenty to be had.
