I think the idea that PC has gone wild is completely overblown. If people are more careful not to be racist, that’s good. If that means we end up missing what would have been a few really funny jokes, it probably also means that we miss out on a thousand garbage racist jokes. 300 hours of video are uploaded to youtube every minute, it’s not like we’re going to run out of things to watch.
I keep saying this in different threads, but the only test that never returns a false positive is a test that never returns a positive. The example you give of people accusing a black man of wearing black face is an example of how people can get things wrong. Another example of how things can go wrong is my entire childhood being full of mildy racist and extremely homophobic jokes in the school yard, in movies and on family sitcoms.
People think we’ve crossed a tipping point where anti-racism has gone too far when we haven’t even met in the middle yet.
And when it comes to politicians, I truly wish any politician would resign over something this stupid/awful/embarrassing. We hold them to a lower standard than we hold gas station employees.
