Earlier today I read Lisa Selin Davis on Democrats and gender medicine. That's a subject that I'm not going to go into because I don't think too often about it. But it did make me think about debate, and what's happened to it.
Public debates on hot topics became a big thing (again) in the 60s. And they were not the kinds of debate where liberals tiptoe around other liberals. Very often what you'd see is, "Norman Mailer and Random Black Panther call each other the Antichrist, agree women belong in the kitchen." You don't miss it until it's gone.
And nobody expected it to ever be gone. Because what it was was open argument. Whether or not they had explicitly agreed to disagree, everyone knew they'd be disagreeing. There was no reason to hold back, to be anything less than honest.
"Liberals tiptoeing around each other" was more a feature of turn-of-the-millennium rhetoric. And of course smartphones have made the problem worse because the groups who discuss things amongst themselves are now so much more homogeneous. And then when a truly extreme idea arises, no one knows what to do with it. Except maybe give in.
