Readers know of the phenomenon at college campuses regarding charges of “microaggressions” and “triggers.” It’s been going on for a while and is part of a growing censorship movement in which professors, administrators and others are accused of racism, sexism, homophobia, classism, gender bias and ethnocentric thinking, among other things. Connected is the rejection or harassment of commencement and other campus speakers who are not politically correct. I hate that phrase, but it just won’t stop being current.
