"...we should tell students exactly how to behave and tolerate no disorder"
Which is exactly what all successful schools tell students of all races. Tolerating misbehavior in minority students is racist -you're telling them they're not capable of good behavior like the white students. Which we all know is wrong. They can and will behave if that's what's expected and required.
Its like the notion of telling black and Hispanic students they don't need to be fluent in proper English (verbal & written). I tell my own children its important, so what would it mean if I tell minority students it isn't important for them?
