Prejudice plus power, when pushed to its logical conclusion, means antisemitism isn’t real (for example). If a black guy hates Jews, he can’t be racist.
Or again: if a Tibetan in China hates a Kazakh or Uyghur, she can’t be racist.
This is simply not convincing at all.
I even had to write a satirical micro-history of the prejudice plus power thesis recently.
