Political correctness is simply calling someone an asshole when they are being an asshole. I can remember when some sports writers refused to call Mohamed Ali by that name. It offended their sensibility, and so decided to be offensive in return, or as we would call them, assholes.
I agree. But there's more to the story. It has consequences that might not be so fun.
Example. Racism is about opinions. It's not about what words are used. When I was young the word for black people in Sweden was "neger". It had no connotation either way. A neutral word.
Then we got MTV in the early 90'ies and Sweden was suddenly exposed to a flood of American media, and the English word "nigger". Then started a transition where people started equating the English "nigger" with the Swedish "neger". If you know anything about European languages and the words for black, the racist assumptions is odd.
After this we got a transition period when older not racist people (who didn't watch MTV) were called racist and didn't understand why.
The Swedish "neger" discussion high-lights the issue. The Swedish PC people didn't care whether people were racist or not. They only cared what words people used. Sure, words matter. But context also matters. USA has a context that Sweden doesn't. If I tell you "din mammas fitta luktade get när jag knullade henne" you're not going to get offended, because it's not a language you use (I hope).
The Swedish PC brigade were using the word neger to bash people. It is intellectual snobbery. Either you are well read, well eduated and intellectual and know how to navigate the offensive words of the day or you reveal yourseld as an uneducated idiot. I wonder why the people most angry about PC is the uneducated working class? Each time they speak publically they are walking into a mine field of faux passes they don't master. Good intentions won't save them.
PC is being used as a bat to bash educationally weak classes in our socieites. I don't know about you, but I'm not cool with that.
I think there's a good test we can use for if someone is a pc-nice person or a pc-asshole. If you watch your mouth to not say offensive shit, you're a pc-nice guy. If you are listening for trigger words, rather than trying to understand what is meant in what other people are saying, and then making a show out of it, you're a pc-asshole.
Being offended about Mohammed Ali converting to Islam and joining the Nation of Islam is perfectly fine. We're allowed to have opinions. The Nation of Islam is not your garden variety Islamic congregation. They are not nice people. We have to be able to say that without being labelled Islamophobic or racist.
Most PC debates are more about words being used than what people mean. It's possible to use racist slurs without being racist. It's all about context. This seems to be completely lost today. Anybody saying the "n-word" is saying "nigger". They're synonyms. A world where one is ok to say but not the other is an insane world. We're so wrapped up in pseudo discussions and debates about trigger words that PC has turned into a joke.
That was a long rant. But this fear of not being PC has led to an inablity to talk about things in a language most people understand. That's what I took away from the documentary.
