I have already explained why this happens, it's because ethnics tend to have worse traits, but what racepillers state, is that being ethnic is a bad trait.
Women seek the man with the best genetic quality, they aren't concerned with tribalism. This is further proven by the fact that blacks (who don't have micropenises, who aren't shorter and who don't have any negative traits) don't share the same difficulties as most ethnics.
Ok, fair enough on the assertion that a lot of ethnics have worse traits, at least physically, and in terms of facial looks. But, what about the blurb on the black pill tab on this site where they show the tinder swipe matches of a White model, and Asian model respectively. Both were very attractive dudes, both should slay? Also the polling when women are asked about their preferences, and it is not raw data from a dating site, but a survey, and they express the same bias against ethnics.
I think tribalism does play a part. In Japan gaijin (Foreigner) hunters are looked down upon by some natives. Same thing with Cynthia bringing Tyrone or Chang home to Mom, and Dad. I won't elevate it to bigotry, but I will say that there is tremendous social pressure in all groups to keep with your own race or group.
Also had to remention that honestly some pretty high caliber Asian dudes on that Asian male White female site lamented their diffficulty getting White girls. It was not a matter of socioeconomics, it was including aesthetics. As a generalization a lot of Asian guys are small, and may not have chad faces, but some guys are objectively better than some White dudes in the face, and build as well. They still struggled a lot.
This also makes me think of another point, and it is local, personal, and so socioeconomic culture. I have lived in a lot of different neighborhoods, and been exposed to lots of them. Middle class primarily, but wealthy, and poor White, poor ethnic areas too. Do you think a hot Latino girl from the bario is going to want to date a quality Brad with a good future? A White guy that is better looking than her thugmaxxed 5'2" cholo bf? No way, but Brad has superior genetics. Same with Cindy the trailer park ho who is used to Cletus, n Bubba, she ain't going to date Brad the college boy, and she sure won't date Chang or Tyrone. It ain't happening man.
Not saying it is wrong, there is no need in my mind to absolve White chicks or whatever of oreferences, but there is a legit basis for the race pill. I guarantee you Korean dad is gonna lose his mind when his daughter in med school brings Tyrone home for dinner. Swing swing choppa choppa man.
