I have to say that there is some "racial profiling" in schools in a couple of major ways:
1) Certain attitudes and actions are considered "acceptable" among many Blacks, including a little more outward vocal and physical expressiveness, which is sometimes misinterpreted as being too loud or even violent by Whites.
2. There are sometimes double standards and there are numerous instances where a Black student was disciplined more harshly than a White student for the same offense or in a Black-White conflict.
These things have happened, but it would be no more fair to paint all stories like this with the brush of "racial profiling" than it is to use the brush of theories like McWhorter's. To me both have some truth to them but neither fully explains the problem.
No, whites do not misinterpret the vocal and physical behavior and attitudes. Those attitudes and behavior are simply not acceptable to whites. That's just a fact, and no posturing or 'understanding' is going to change whites reaction. If blacks want to persist in those attitudes and behaviors in institutions governed by white standards, they cannot complain of punishment.
Actually, whites often see such behavior among whites -- they call it "white trash". It's not accepted in middle-class white society, but I suspect that black society has not effectively differentiated black middle-class culture from underclass culture.
I suppose what ends up happening is that blacks who join the middle-class, end up adopting the white middle-class culture.
Not misinterpreted at all - Correctly interpreted as disruptive behavior in a classroom.
