" I imagine some wealthy descendant of a colonizer who's never set foot in the country deciding they want to go to the Olympics as an equestrian or some such, and buying their way on to the team."
That one sentence is so racist in so many ways:
1. Using the anti- white racist slur term "Colonizer."
2. Assuming that whites would only want to be in the Olympics as an "Equestrian or some such," in other words, in a less physically- demanding field.
3. Assuming that whites are so physically inferior to blacks that the only way any of them can get on an African Olympic team is through bribery.
