I appreciate the debate and candor guys! That did help me to understand it myself. I know I have heard it from other people that they just aren't attracted to *insert race here*, while in reality they more likely find certain traits appealing and are over generalizing an entire race based on stereotypes (or their own experiences). I personally have perceived superficial preferences but when I meet someone who is genuine, whom I also share interests with, those preferences generally fly out the window.
I'll admit the initial question was left vague on purpose to encourage response. As a white male who grew up around very little diversity in central Kansas, it is interesting to both determine where my own perceptions of preference have come from as well as noticing how they have changed.
Just to continue the conversation a bit, if I don't find a specific accent attractive and that accent is related to a certain group of people. . .is that discriminatory? It is sterotypical, but I know many women who go goo-goo over certain accents but are equally repelled by others.
