@ArcMother @blueemu @aleen @jargoggles I do actually have a lot of experience with clinical narcissists. And childhood bullies. And college Republicans. And then there's the people we see on the YouTube.
Yes, juvenile insults work well with a small subset of those people, but even childhood bullies can get pretty good at parrying a juvenile insult, even one delivered with calm composure.
I'm not nearly as good at knowing what people are thinking as you, though, so I guess I'm wrong.
