Hmmm... I wonder if I have anything to do with the creation of this thread.
I'm caucasian and have a mild preference for asians. The "mild" part probably comes as a surprise to those who know that I've been so corru- I mean, influenced by my hobby that I look to Japanese cosplay blogs for my beauty ideals, but I'm being completely honest here. I've run into women I consider hot from pretty much every race and would say there's a lot of variation within races as well.
(I don't know if I'll ever have kids at this point, but if I do it could end up being interesting. For the most part, my parents seem totally fine with interracial marraiges, but I have heard my dad lament on a couple occasions that his Scottish genes are trumped by essentially everything.)
