It may just be that I've shifted social circles as I've aged, or hell even that I've become cranky, but I've noticed a huge decrease in debating ability over the past 20 years or so.
I can't quite put my finger on it but I guess it feels as if labels, black and white thinking, and absurd levels of tolerance have proliferated as mind killing tools.
The point I am making is not that people are unwilling to concede, I don't see much change in that, but that debate itself rarely happens.
It's far more common in my experience for someone to attempt to shut down debate with a label like racist or woke, or draw a connection to a political philosophy in an attempt to discredit, rather than actually try to give valid reasons for why I should adopt their position.
Back in University I found that to be far less common. Looking from the outside in it seems as if nowadays campuses have become much more reactionary.
