Hm, I'm not sure I agree. All of the nations outside Westeros either written as ambiguously European themselves (e.g. the Free Cities) or heavily exoticized, through which their White Saviour (Daenerys) must ride with her unabashedly barbarized version of the Mongol horde to save them from their evil ways with her more enlightened ethos.

I love ASoIaF as much as the next fan, but I don't try to tell myself that it doesn't have its own issues re: race.
