Frumious Bandersnatch
I read of a small group discussion in a university class in the 90's in Minnesota. People were asked about how they felt about homosexuality. A student said he thought it was a psychological problem for which people ought seek treatment. He was disciplined for some charge that didn't quite equal hate speak.qwe said:(as well as possible negatives? why don't you explicate these negative impacts? the positives are sort of obvious)
Organizations with a heavy emphasis on political correctness are often at the same time trying to put out a message that all ideas and cultures are valid. (Except well not THOSE ideas). If Camille Paglia were a untenured instructor many places a lot of her ideas would result in dismissal. I don't dig every Paglia idea but I do like people who agitate against group think quite a bit.
A problem here is some people start to think every edgy contrary to possible group think positions is worthy of a lot of time and energy. Most aren't.
I'm getting off track there, a problem with political correctness is that it can appear or actually be Orwellian. Making and applying rules about speech and their underlying ideas is always going to seem uncomfortably fascist to many people. A complete comfortableness with enforcing political correctness would scare me, but some ideas expressed overtly would shut a lot of people out and create lots of distraction. It is no easy thing.
