I agree with you L 100%. Except in this case, a discussion about faith and God, the more you can be on the same page the better. Saying one is a Christian is almost meaningless as mainstream protestants, JWs, Mormons, catholics, the Westboro Baptist Church, and snake handlers are all self proclaimed christians. Now, in answering a very personal question (in that there are few things in life more personal than religion), UP had allowed everyone to at least grasp the platform of what he believes.
I know he's dealing with apologetics way too much, and that whether he's a methodist or lutheran or catholic or snake handler had no real relevance to the discussion as it stands right now. But should that change, it's nice to have a baseline for his beliefs as it would be nice if he had a baseline for whoever he was talking to.
That's my thoughts anyways.
