I am currently in middle school, and as many of you know, profanity is thrown around in middle school like clothes in a dryer.

My religion prohibits me from being profane, how can I tell my friends to stop swearing so that I am not influenced by their actions?

For all those wondering what my situation is, I am an 8th grader living in Minnesota. The people I am asking to stop swearing are people who will not believe in my religion, but I would like to still keep them as friends.
