There can be many extraneous answers to the question, but the root of all answers lies in this: progress.
It is precisely because there has been so much progress made in which asian women have become more educated, more attuned to the western standard of beauty, and more liberated that they started to have a higher standard in men. And here again we enter into a little controversial topic: white men are superior to asian men, black men, hispanic men, etc. That’s the fact. And even if it were not the fact, does it really matter? Remember, women choose their mates. So the fact that the most beautiful, feminine, and universally desired women—east asian women—overwhelmingly prefer to mate with white men needn’t even be pronounced. It will simply become a unspoken truth, the kind of truth that you carry stealthily with you over the night, the kind of truth that you hold your hand over her mouth, lest she screams too loudly, the kind of truth you dare not shout in a public square or a crowded theater, the kind of truth known to all but uttered by none. Asian women and white men are natural fits for each other; they together represent the progress toward the next stage.
And this is where progress pushes to a biological end. Despite all progress by feminism, women still overwhelmingly tend to mate with males who are superior to themselves, so you see why female Ph. D.s marry male professors, female CFOs marry male CEOs. Women in all cultures and races still tend to marry up, so that means if a woman is highly educated, she would not want to mate with someone who is less educated; if she is very powerful, she would not want to mate with a man who is less powerful than she is. So progress has pushed asian women to the frontier of power: she has become more powerful than asian men; she has become better educated than asian men; she is more attuned to the western standard of beauty than asian men, and naturally as a biological rule she would not want to marry down and mate with some ugly dirty asian men.
Since White men are by far the most superior males, and therefore the most desirable to mate with, then naturally every woman would want to mate with a White male. And since asian race is inferior to white race, since asian race is the submissive race complement to the dominant white race, then naturally asian women, who are superior to asian men but inferior to white men, will choose to mate with white men.
Herald shall they one day with flaming tongues, the future belongs to white men and asian women. This is the trend of the 21st century and those degenerate races that cannot embrace this trend will simply be eliminated.
