cool idea. So that we know when a debate is multi-religion one!

Like when Liberty was here, and when Aramadick20 joins, it will be an all Abrahamic religion party!
I think it helps to identify a users perspective, particularly when we have different people floating around at different times - it sometimes hard to keep a track on things, particularly for other new joiners who dont know anybody yet
I disagree. Debates should be debates of ideas, not of people (including people's positions, unless they choose so). It won't help anyone if assigning an automatic position would make people put words in one's mouth. It's never this simple anyway.
As an example, I might be tempted to throw ideas supporting a particular position, because I see certain arguments as valid enough to be worth adding to a discussion. It won't "mean" that I am always convinced 100% of that - or of everything that perspective comes with. I just see why it seems valid and add it to a discussion.
