Taleb is learning that some races are more equal than others.
For example, here's a story from Quebec:
A high school teacher in Montréal-Nord is being called out after using the N-word multiple times during an online class captured on video. The man in the video has been identified as Vincent Ouellette, a history teacher at Henri-Bourassa High School, a large and diverse French school in the city's northeast end.
You see, only Black people can say nigger without consequences. If a White person utters that word, then Black people combust:
"I understand it was in an academic setting, but to still see a white person — someone's white mouth saying these words — I was taken aback. It was wrong to me."
Instead of shrugging and moving on with her life, she is basically saying that White people can't say that word because Black people are feeble and fragile. Also, more Affirmative Action please, because Black people are dumb.
This is one reason why diversity in large numbers doesn't work. Sooner or later, you get utterly different academic and legal standards for the diverse races which only accelerates the inherent conflict between the groups.
