Is Atheism Self-Contradictory? Debate w/ MadebyJimbob

I recently had a debate with Madeby Jimbob where he attempts to show that atheism, naturalism, determinism etc. is a self-defeating position. Warning: this debate goes heavy on metaphysics, truth, epistemology, and then for some reason gravity there at the end. It was fun although I still don't quite understand Jimbob's point. I don't see any contradiction between determinism and knowledge of truth, but then again metaphysics is not my forte, so I'd really appreciate your comments and feedback on this one.
