Yeah, there were more than one question where I was looking for the hidden third button. "Do you believe that your own redemption lies in your own hands or those of a superior power?" indeed. Yikes, I believe that the superior power created a system in which redemption is mine to accept or reject, so which one of us deserves credit for my salvation? (I picked God, of course; my momma didn't raise no dummies.)

The map does seem odd to me too. As to your question, I should think that Islam should be lumped in with Judaism/Christianity. (Indeed, I think that we should phase out the word "Judeo-Christian" and replace it with "Abrahamic", but we'll save that for another day.) I fell under Taoism myself, which is well-observed. I don't practice it at all, but you might say that if Christianity is the steak that I eat then Taoism is the marinade that it was soaked in. But combining philosophies (i.e. Fundimentalism) with religions (i.e. Scientology) is rather a mishmash.
