Nah. This small subsect of people exist in every culture. Its not en masse in any culture including our own as is evident by the overwhelming marage rates within the community. Furthermore, Each ethnic group has a sect thats infatuated with an element of every other ethnic group. Its human nature. For every balck woman infatuated with femminine korean dudes through kpop, there is a duplicate korean man in incheon or busan infatuated with big booty black women through hiphop or reggae.Seriously. I don't ever hear Asian/Latino people en masse praise and simp for black people
Among whites, you have some white chicks that can be exclusively into black men (sometimes in a fetishy way), same with some white men and black women. But even then, they don't always look up to them as being better than there own, the way black people do with others.
You may need more exposure and interaction with these groups to see it. For example, i speak both korean and japaneseand i am privy to their convo on their mediaoutlets. I have also had korean and japanese collegues who corroborate these stories. But if you didnt speak the language, or barely had contact with these groups in your personal life; you would incorrectly percieve radio silence from their direction.
. Ive persoanlly encountered many of the latina(s) who do this. Any brother that has been to korea or japan or parts of LA has experienced this with asian women. And on many occasions these sects of women excplicitly point the black man as better than their native stock for any random reason ranging from our hair, to our skin tone, to our fashion , to our dance, to athleticism , to our better treatment of women, etc.
Ive also encountered white men who exclusively date black women . Tho i must admit that i did find this extremely weird the first time i encountered it . But i suppose that was exposure i needed,

But Again, with enough exposure you will see this stuff. And its endemic to each group. For example, i breifly went into a reddit rabbit hole a few weeks ago and discovered that indians are having the exact same coli topics as us but reffering to pakistani dudes/women whom they allegedly despise. This prompted me to check out the pakistani side and they are having the same debates as both the coliBrehs and the Indians on self hate and hyperbole reffering to lust for the other side. And this is just the superficial english stuff, so i cant even imagine the data i was missing because i dont speak urdu or gujarati.
