In short, the white students talk about the stereotypes they have learned, and the students of color reflect deeply on the cruelty of race in America. When white students initially suggest that they personally did not do terrible things, the students of color fire back with both barrels. White students have come to realize that the pieties their parents taught them, such as an honest day's pay for an honest day's work, apply only to whites in America. Let the children of the guilty denounce their parents. Let the victims stake their claims.
Reasonable people disagree on profound questions.
These are not issues for indoctrination. This is a return of in loco parentis, with a power unimagined in prior ages by the poor souls who only tried to keep men and women from sleeping with each other overnight. It is the university standing not simply in the place of parents but in the place of private conscience, identity, and belief. From the evidence, most students tune it out, just as most students at most times generally have tuned out abuses of power and diminutions of liberty. One should not take heart from that.
