pvp is causing much, but also it is a case very simillar to religion and i think we'll have to take it ti'l the end of wow. i for one had no problem during the third war when peace lasted beetween us elves and the humans, bacause of me wanting to save the greater part of my people i chose to help the ones who were betryed by kael'thas and the other high elves along with many humans didn't like that.
(if you don't like the rp, just read only the first sentence)
