Is it fair to say that white people are literally “tight-assed”? Do they have a tendency to hold themselves in, to restrain their bodily selves in ways that other people don’t?
If so, why do they do that? As a person who lives inside a “white” body and has also studied the history of whiteness, I will offer here some tentative answers to these questions.
Ahead of his time, [Rush] argued for the abolition of slavery, and the removal of freed slaves to black colonies, where they would be trained into becoming more civilized beings. This training would include learning to restrain their bodies, as white people did.
