I can't stand people who talk in slang
How do you feel when talking to people who talk in slang?
I want to make them shut up.
You shouldn't judge people based on how they talk. People have a right to communicate how they want to without being judged. Maybe you can think about why it bothers you so much so that you can let it go.
I just want people to stop saying ''bruh'' so much. It's annoying.
I can empathize with you on that but it's still wrong to tell people what to do. In fact, the more you bring attention to it, the more they will want to do it so it's better to wait until the fad goes away.
