Being an Asian guy (we're supposed to be one of the lesser desirable races to white women), I notice a funny trend.
It is specifically white women in "racially diverse" areas that have this massive ego, see ethnic men as below them, are full of themselves, and are often the choosiest about race. You hear of Asian men and ethnic men struggling to get white girls in California and NYC the most because you have a ton of low class immigrants and poor minorities that boost the ego of white women, make them feel better than others.
The funny thing is, you even see this among white latinas and white women from areas where whites aren't common.
White women from very white states like the Dakotas or Montana would not hesitate to date a sexy Asian or sexy Indian guy but the ones from NY and California would.
It is like American liberalism makes white women that look good hate ethnic men, maybe it's because Hollywood has such a big impact there.
What's weird is that I see a Trump presidency, assuming he carries through, benefitting cool ethnic guys the most. When there aren't thousands of rapist refugees, illegal brown people, and lower class immigrants flooding into an area; white women are more open minded to giving cool ethnic guys a chance.
