The real problem is that you can't enforce lore without alienating the people with whom you play.
I play a Grimtotem tauren, and so my bloodthirst for the death of the elves and my desire to take back all of Kalimdor for the tauren is real and valid, I'd hope. But those who play bloodthirsty Tauren are just as entitled to their playstyle as you are to yours, Rowne--for the most part, the Tauren in my (evil) guild are playing characters with lore as their background who all have reasons to be bloodthirsty, just like the orc warlocks and warriors and trolls and etc. who want to kill all the Alliance. (There are certainly those who are not following the lore, and while I think that's not so great, eh, who am I to say so.) The problem with saying that one of the races is one way or the other is that they're just like all people: every race has its bad folks and its good folks, and those who walk the line. My character wouldn't WANT the war to be over, because he wants all of the pink-skins and long-ears dead.
I'd probably stop playing if there were committees to enforce lore on this game's RP servers. My creativity flourishes when I have the constraints of the lore imposed on me, I think and hope, but others' creativity gets stifled, and I'd hate to see that.
I'm on an RP server, too; I started on Cenarion Circle and moved to Twisting Nether when the RP-PvP servers opened (or truthfully a few weeks after). On CC I found the atmosphere to be more mature than on a regular or PvP server; on TN, I've found a truly, truly awesome (and pretty big) guild to play with, so even if we have some PvP server a-holes, I can turn off /general and have the best time I've had in WoW.
Like Rowne, I find a good session of roleplaying much more fun than any instancing or BGing or anything of the sort, and also like Rowne I think having fun is more important than adhering to any crappy "RP rules" people seem to make up on the fly. Staying in character is pretty important to me, though.
