The senseless fueding

I don't understand it. The World (of Warcraft) is about to undergo the worst devastating attack it has ever had to endure and yet the two sides still rage war

Its seriously compared to say.. Aliens coming to earth with the intent to exterminate the human race and all the sudden France gos "You know what....? EFF AMERICA!" and launches an attack on the US instead.

I can sympathize with the reasoning "We fight for resources" But COME ON, the people of The World (of Warcraft) have to be the stupidest, most racist civilization of NPC's i have ever seen in a game
