Let me know when you make those articles public. As I might have told you (or at least some other commenters), I have an article coming out soon on agnosticism's relation to atheism. It all depends on how "agnosticism" is defined. Agnosticism proper ends up being specious scientism, so it's no valid rival to atheism.

Moreover, even if no one knows what exactly caused the universe to happen, that doesn't mean we're perfectly in the dark about every possible explanation so that we'd have to give 50-50 odds to each of them. We can suspect that the matter is beyond our comprehension and still dismiss monotheism for being a badly-form, internally incoherent contender. That kind of agnosticism is thus consistent with atheism.
