Slang Should Not Be Banned in School I do not think that slang should be banned in schools. In order for that to happen, people would have to all agree on what slang is. This could be a very unfair process because people from different economic, regional, and educational backgrounds have different ideas about this. Students in the same school speak in different dialects where some things are considered acceptable in one dialect but not another. I think banning vulgar language or swear words is okay, but not slang in general.
