OP, Im mormon, say it proudly. Mormons are like every other religion, there are normal mormons and then the weirder kind. Im a normal kid, I've partied: drinking, smoking, attempt to entertain the ladies lol.
The point im trying to make is, that its just our religion, we aren't a cult. Generally normal people won't try and convert anyone unless that person shows interest in the church. As for making friends and being part of society, I have best friends who are catholics and other religions, I have best friends who are Mormon. It doesn't effect anything. Of course I don't party anymore, and Im actually about as good as it gets, other then cussing. I feel like my reasoning should help. hope it does.
