I don’t have direct examples because I suck at googling, but what I saw that made me think of this was an ancient Greek philosopher insulting another, presumably in a rude tone, but still translated to look super polite and old timey. The explanations people have given here have really shed a lot of light for me on why that is though, so it makes sense to me now.
Yeah, and the worst is when people are talking about something I know a lot about, getting virtually every detail wrong, and I have to resist saying anything because I know my input will either be ignored, or worse, straight up unwelcome.
Luckily the blessing of being dumb as bricks is that that doesn’t happen a lot, but I sure hate when it does.
