I only skimmed the previous posts since it's too early in the morning for me to fully concentrate, but I think a lot of it has to do with asian society, at least when dealing with 1st or even 2nd generation immigrants.
My fiancee is Korean and she doesn't like asian guys because in *her experiences* the males are seen as superior to the females. She's very "americanized" because she came over when she was young, and that 2nd class citizen thing doesn't mesh well with her mindset.
.... and cause we have bigger peckers, like PhilMcGroin said
