I chose spiritual, rather than LDS or even Christian for myself because I learn from conversations with people who are not just in my own faith. Now, I wonder what I've invited. Help? Can we change our three?

I recommended Christian for you, and I think it still fits. I may be taking a risk here, but despite the desire you may have to distance yourself from the things you perceive about other Christians, some of it really may just be your perceptions and not wholly accurate. Just like many Christians don't believe LDS members belive in Jesus Christ, which we do, those "stereotypical" Christians you're avoiding may be just that--stereotypes. 

Face-to-face or computer to computer, I think most of us genuinely act Christ-like, and the example you relate is probabaly the exception. (Note. I'm not an Obama fan, but I've never flown off the handle. I just let those differences be differences and move on and enjoy your writing and take what I like from it.)
