The one area I *do* think actually has good evidence to support "racism" (or something something race-based preferences) is sexual attraction. It does seem like black women are pursued less on the dating and sex markets.
Not sure?
Anecdotally though, after having been in various forms of sex work for years, it does seem obviously true that black girls earn less money than white girls, even if they seem to be the same attractiveness level/doing the same marketing.
