You don't eliminate biases and prejudices by making them the center of attention and by politicizing scholarship and teaching. The decline of civility on college campuses has come from the very people who claim to be the champions of justice yet advocate racial polarization and declines in standards in the name of diversity and other pseudonyms for quotas. Somehow this belief exists that blacks and other minorities will never set foot in colleges again if affirmative action is overturned. That is, I think, a blatantly racist attitude. No class necessarily needs X members of any particular group to present divergent viewpoints.
Some classes do call for discussions and readings in race or gender.
We are freed from biases when higher learning becomes grounded in values that encourage intellectual balance and rational debate on contemporary issues. Biases grow worse when one attempts to cure them by political and ideological conformity. Many are the ways to achieve diversity, but discriminating on the basis of race is not one of them - and that is really what these protests at Penn State are all about. But to use some real or suspicious threats against a few students to extort money and promises from a university is an act of shame, not protest. And to accede to those demands, as Penn State University did, is not an act of courage, but an act of cowardice.
