This studio is to protest against cursing. You know WHY I did this? These can harm some people, and not just young children. Curse/swear words aren't always used when joking around, and one other way it's used is by cursing at someone, and that can hurt their feelings. That can become a form of verbal abuse and it can start a chain reaction between others since they'll think of it as a good way to get their anger out.
Speaking of chain reactions, this can happen between little kids who don't know what curse words are. They can overhear someone else say it and think that it's okay to say and start saying those to other people.
