It all depends on who is compiling any list. Their own tastes will dictate. An Asian man stating his own women are more attractive than black women is simply a reflection of his preferences (it isn't shocking that he would prefer his own women over any other), however, it's all about how it's stated publicly that raises the ire of others. Part of the problem is people feel so compelled to voice EVERY opinion they have publicly, then get upset when there are consequences for it. There's no need to talk so much about your personal choices - just go about your business.
"The best kind of pride is that which compels a man to do his best when no one is watching."
