One might object that there are important group differences among blacks that a white man simply cannot detect. I have done my best to find them, but so far as I can tell, they dress the same, talk the same, think the same. Certainly, they form rival groups, but the groups are not different in any discernible way. There simply are no groups of blacks that are as distinctly different from each other as white “nerds,” “hunters,” or “Goths,” for example.

They're all hard wired the same. There's no variation.

I was trying to teach a unit on British philosophers and the first thing the students noticed about Bentham, Hobbes, and Locke was “Dey all white! Where da black philosopher a’?” I tried to explain there were no blacks in eighteenth-century Britain. You can probably guess what they said to that: “Dat racis’!”

One student accused me of deliberately failing him on a test because I didn’t like black people.

“Do you think I really hate black people?”

“Yeah.”

“Have I done anything to make you feel this way? How do you know?”

“You just do.”

“Why do you say that?”

He just smirked, looked out the window, and sucked air through his teeth. Perhaps this was a regional thing, but the blacks often sucked air through their teeth as a wordless expression of disdain or hostility.

Apes and monkeys also do that when they're pissed.
