Randomly found this clip of Tucker Carlson interviewing Adam Carolla and Dennis Prager:
Carolla and Prager ask: What if we all stopped apologizing? - YouTube
It's actually quite a profound revelation. An ordinary person would naturally wish to offer an apology when they know they've transgressed in some way. It's because ordinary people count on a presumption of good will in their dealings with others. It's mutually beneficial, and indeed more pleasant, to deal with someone who values the exchange about as much as you do.
SJWs don't think like this at all. In the mind of the SJW, every social interaction is an exercise in power dynamics. It's not a friendly greeting, it's a clash of wills which must result in one side defeating the other. Therefore they attack the presumption of good will, because that leaves ordinary people vulnerable. It's a social sucker punch which only hardened culture war veterans will be prepared for.
The reason I think this is so profound is that it reveals the true goal of the SJW movement. They want to destroy trust between individuals in society, thus leaving society as a whole vulnerable. If we can't trust in the possibility of mutually beneficial relations, then there is no basis for trust of any kind between individuals.
