I don’t think it’s just public schools that won’t discipline black children. I ran into this at my daughter’s Christian school when she was in the 6th grade. I transferred her at the end of the school year because of an incident that happened just prior when the incident would have been an assault in today’s world, not so back then, but all they did was “talk” to the boy.
When bad behavior is not punished, the inevitable happens.
As any parent knows.
