I started in public school specifically bc my mother didn't want me to turn out like you. No disrespect, but... sir, you sound like a c00n.
I went to school with the 'best' rich preppy white folks and I'd prefer my kids around honest people. The effects of placing young black kids in the dog-eat-dog, Cruel Intentions world of the most exclusive independent schools has not been widely studied (that I know of), but, as one who survived mentally intact, it wasn't easy. Those who are still normal have been cynical, distrustful of wp, and somewhat woke from the beginning. The lost ones sound like you.
