Thank you for pointing out perceived fundamental flaws. It's so much more helpful than disputing technical details.
1) I know that. However, I would guess that most people here have fully privileged atheism since the time they started considering themselves rationalists, and this is a big difference.
2) I was aware of that too; however, thanks for the specific links. I certainly got on here loudly proclaiming that I was religious; however, my original stated purpose was not to start an argument. That said, I really was asking for it, and when people argued, I argued back. Where I live it's so hard to find people willing to have an intellectual debate about this sort of thing. So if I did something "taboo," I apologize. But the reaction I've gotten suggests that people are interested in what I've said, and so my thoughts were worth something at least.
I suppose that when this thread resolves itself I'll make a grand post on the welcome page just like AspiringKnitter did.
Let me see if I can explain my objection to (1) a different way. Rationalists do not privilege atheism. They privilege parsimony. This is basically a tautology. The only way to subscribe to both rationality and theistic religion is compartmentalization. Saying you want to be rational and a theist is equivalent to saying you want to make a special exception to the principles you follow in every other situation when the subject of God comes up. That's going to take a particular kind of strong argument.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
