I think Obama is Christian because he wanted to be in poltics. I think had he just intended on being a professor, we would have seen him more 'agnostic' (or just non-practicing)than anything else. I think the idea of family and community is something he truly believes in, but I don't think he feels that you also need Jesus Christ the way real hard-core Christians do.
That doesn't mean he's not religious, it just means I don't think it would be a priority in his life if it wasn't a priority of politics.
I certainly don't hold his lack of true-blood,hard core devoutness against him.. nor do I hold it against him if he 'fakes' it. I find it more of a sad commentary on our part that we would have our pols fake it rather than to be adult about it and move away from where they are all forced to have a Jesus fish on their bus and a flag-pin on their lapel ...
if he was Muslim I can't see that I'd care...any more than if he was Jewish... but, I do admit that if he was a Jehovah Witness,Scientologist,Mormon.. well I would have issues.
so maybe I need to be a little more 'adult' myself as well...
