To the subject of racial/ ethnical self-hate, in general- I mentioned a few times one guy whom I know, a proper self hater. I think this phenomen exists among some eastern-Europeans, especially Slavic. Its not common in 'real world", more common is sort of feeling inferior in financial aspect- but not racial or ethnical, however some people who are 'into' genetics or races may express this biological inferiority.
Probably it is result of pre-Nazi and Nazi racial propaganda, plus American racist attitudes from XIX century. Nazis were mainly antisemitic and anti-Slavic (obviously they disregarded all non-whites, but were not bothered with Africans or Asians too much), Americans in XIX century had wider racial prejudices,included people 'forgotten' by Nazis, but again- among them were eastern Europeans too.
So its like, EE score minus two points in the ''racist' game, one from Nazis one from early Americans, while eg southern Europeans or Irish score minus one point and German/Anglos zero points. Jews score minus two too, and other non-europeans too, but as they are 'obvious' object of racism, it may bother them less.
Anyway, these 'scientific researches' of XIX century racists are valid mainly for XXI century racists.
