You're joking, but you're not wrong.

The lack of emotional (and explicitly confrontational) experiences in modern society are underdeveloping skills to deal with them.

Consequently, you get childish spats over what should be a technical disagreement, because people aren't comfortable saying "I think you're wrong, but I respect your opinion. Here are the reasons I think you're wrong..."

As the quip goes, anonymity and the lack of physical presence turns everyone into an asshole on the internet -- and then we raised most of the world on the internet.

It's true that people are less and less ok being confrontational. I don't mind having a spat, but it is becoming increasingly rarer
