I have my own views on Obama's take on religion. And no, I've not read his books. I see him as sort of a cultural believer, a step above agnostic... but also not agnostic. Spiritual (I say this as someone not spiritual even in my little toe). I don't see him as a potential victim of what I think of as religious tharn. I guess I see him as seeing the good in religion.
I have a long time atheist pal who told me, maybe ten years ago, that she'd come around to the point of accepting that people are religious, seeing good in a lot of the morality promoted by religion, both for itself and for warding off of chaos as a societal good. (Haven't talked to her lately, wonder what she thinks by now.)
I probably grunted or mmm'd, but of course I see that too. I think it is the tremendous level of shunning, even hatred of others, the proscriptives, that irritates me with religions, certainly not the 'do unto others' part.
Well, we'll see. To date, I didn't see these invocations as threatening - more as a kind of, heh, warp to woof.
