By the way, BuckettMonkey, the orcs you mentioned were saved/converted by Eldath (a god of peace). If a race requires divine intervention to be shifted away from evil, I'd say that's a pretty significant indictment of the race as a whole.
I don't think you will win this one, Ragitsu, because WotC has pretty much decided that everyone decides for themselves everything in FR and D&D. No lore is Canon and no rules are set and everyone decides for themselves whether alignment drives the race to be good or evil or whether each person drives the alignment.
Are there even good and evil realms anymore? Are devils even evil? What about hags? Mind Flayers? Intellect devourers?
