Ok. What's a revolver? Asking for a friend.
Yes, I know that both are one trigger squeeze, one shot. Pistols, as opposed to revolvers, hold more ammo.
The point of the redundancy in my original meme is that "semi-auto" is the dog whistle word that leberals use to scare people. When they say a weapon's "fully semiautomatic" then you know that it's extra special scary.
