Similar to public farters, these people need to know their audience. If you're in a room full of grunters, grunt away. But if your annoying people and making a spectacle of yourself, stop it. Why are you grunting anyway? Are you trying to show off? Because it's really not necessary. We get it. It's heavy! If you're lifting something that causes you to emit an unpleasant sound, why would you want to lift it anyway?. If I have to lift something at home that would cause grunting, I get someone to help me with it. It just aint worth it.
In the new world, gym grunters will be pointed at and made fun of. And they aren't allowed to beat anyone up.
AND SO IT SHALL BE WRITTEN!
