> For example, at the high water mark of political correctness in the early 1990s, Harvard distributed to its faculty and staff a brochure saying, among other things, that it was inappropriate to compliment a colleague or student's clothes. No more "nice shirt." I think this principle is rare among the world's cultures, past or present. There are probably more where it's considered especially polite to compliment someone's clothing than where it's considered improper. Odds are this is, in a mild form, an example of one of the taboos a visitor from the future would have to be careful to avoid if he happened to set his time machine for Cambridge, Massachusetts, 1992.
This is interesting. I've heard multiple people say that there have been two political correctness peaks: one in the early/mid 90s, and the other starting from about 2013 to now.
Are we already coming down from our current PC peak? I think we might be, even though it seems weird to say (given that we're still near the peak, so that political correctness is still high). Some evidence for this:
1. There seems to be a larger and larger cultural awareness of the toxicity of political correctness, so much so that it's starting to no longer be counter-cultural anymore, but just a well-represented view. The IDW is becoming more mainstream (which means they need to stop representing themselves as a persecuted group, lest they become stuck in 2017). For the record I'm a huge fan of the IDW. I don't want to see them stagnate.
2. Leftists -- usually blamed the most for political correctness -- are even now able to discuss a few ideas in public that they weren't formerly able to quite as easily: (i) they can more openly discuss the merits of socialism (using the "s" word) and (ii) they are free to question the orthodoxy of traditional free trade. In fact nearly every major candidate for the Democratic nomination has denounced free trade in some way. This would have been unimaginable 10 years ago.
There's still a long way down from the peak, but times feel less PC now than they were say in 2017.
