Eugenics. Specifically phrenology/craniology. Check 'em out. We know it as pseudoscience, but plenty of idiots out there still see "measuring tool" and think "it science", while supporting their beliefs they're a superior race, so it actualy lingers on drenched in irony.
Idk the context of whatever the complaint is, but I just want to point out that people's noses always look way bigger when you take closeup photos of them. It's because the nose protrudes out from the face, so from a normal distance it's just a little bit closer to the camera, but from close up the proportional distance difference and therefore apparent visual size of the nose is massive. If your nose looks big in a photo, re-take it from further away.
"Them" who? Because I'm Jewish and it sure as fuck doesn't bounce right off me.
Maybe you live a life of privilege and aren't aware, but when someone attacks you for something about yourself that you cannot change and didn't choose, it doesn't feel great.
