I agree that this is weird, but in dang's defense, "non-violent communication" is a commonplace term, and has its roots in the nonviolent peace movement. Like there's entire books written about it etc. It's a terrible word choice, I agree wholeheartedly, but given how widespread a concept it is at this point I don't think you can blame people who use it for that. It's like, "WhatsApp" is a terrible app name but I don't cringe when my mum says its name.
It's actually a pretty useful tool. I wish it was called "compassionate communication" or something like that though.
Oh wow seems like the guy who invented it hates the term too: https://en.wikipedia.org/wiki/Nonviolent_Communication#Alter...
