An acquaintance of mine who was born in China's Kwangtung Province has a last name that is common in both China and Korea. His office is a few blocks from Koreatown in LA, but he has no Korean patients. He says that when potential Korean patients call him, they hang up when they find that he's Chinese.
And the Rape of Nanjing by Japan. Japan views Chinese (and all other Asian races) as inferior.
Racism likely exists as a survival mechanism in humans. Gather in groups for safety and fight against the “other.” African tribes kill and slaughter each other. Asians. Whites. Look at Russia and Ukraine who are essentially brothers killing each other by the thousands. Part of depravity of human nature.
But - ironically racist to do so - whites are all evil to the media and our institutions. So anyone evil is, by definition, guilty of “whiteness.”
