Interesting take on the issue, Dave. But I have some reservations about your arguments.

While I think there is some prejudice against Asian males, I don't think that's necessarily related to anime's reception in America, because I feel there is not much solid evidence pointing that way. From what I witnessed in high school and college, there are plenty of Caucasian fans of anime, although they are mostly male and fits the exterior stereotype of nerd. "Nerds," as we all know, are the social Untouchables of highschool culture who form their own cliques. So the letter-jacket wearing Brahmins can hardly be seen mixing with the wrong company. According to my observations , in America, to get into anime, usually one has to be introduced to it by friends, because it still has a low profile. If a person don't hang in the social circles where anime is being discussed, then he is a lot less likely to accept anime later. So I believe the barrier between anime fan and anime non-fan is primarily a social one, not a racial one. Perhaps I am optimist, but I believe people are predominantly motivated by social impulses for good or bad, rather than racial ones.
