South Korea too.

No, they are not. Koreans in the West are the worst among "woke" Asians and the westernized youth in South Korea embrace the leftist narratives they get from America about racist white people.

I only see this among blacks.

It is not at all only blacks who hate the fact that they find their own more attractive when they look whiter. In India a company even stopped selling a skin lightening cream recently due to this criticism. "Aryan" features like light skin, hair, eyes, and European facial features are all preferred throughout the world. Individuals who are not European but have such features are always celebrated for their beauty in non Western nations. This causes many to seek skin lightening and surgery. They are often ashamed that they find their own more beautiful when they look more European and blame Western cultural dominance and colonialism.
