What is with people who cannot understand a **graze**?

Sam Harris does that really weird leftist thing of talking about "what a rifle round does to the body" as an argument against a bullet hitting Trump's ear.

It's so confusingly dumb. A bullet can graze you. It grazed Trump's ear. That's it. It doesn't matter what a rifle round does to "the body". What is wrong with these people?

Is Harris really unable to comprehend basic physical realities like a graze? The idea that a bullet at Spacetime Location A1, just kissing an ear, is different from a bullet at Spacetime Location A2, plowing through someone's lung or whatever.

Related to that is all the leftist discourse about what bullets do to the head, concussive effects from glancing shots to the head, etc.

All of that was in the service of Bullet Truthers. Problem: Trump wasn't hit in the head, not even a glancing shot. The bullet nicked his ear. Ears are attached to heads, but are not heads.
