These discussions about PC speech codes are posted to everybody on campus except for students. The janitorial personnel, the cafeteria workers, the support stuff, the building management. These are working class folks who don’t have the educational and cultural capital or the leisure to stay updated on the politically correct jargon.
Day after day, they hear that they are racist, hate-filled, transphobic, homophobic, evil, etc. Day after day, they are being hectored at work by people of upper social classes about how the basic things they think they know about life are not only wrong but bigoted. And they are afraid to say anything because they are easily dispensable plus there is no way they can win a debate with a person who has a PhD in social justice or whatever.
So they seethe and then they hear Donald Trump ridicule these PC tormentors, and they like it. They think he’s on their side. And it’s not the right conclusion to draw but it’s understandable. And we can heap abuse and burn with righteous indignation all we want. But it only aggravates the issue.
