I see where you are coming from, but then again I think you are wrong. Many kids don't swear. Many kids play with mates from the physical world. Also, video games provide an escape from reality. If you are a kid getting severely bullied and you need to take that anger out on something, it's always better to take it out in games. Shooting games let them picture their bullies faces on bodies and pull the trigger on them, providing a huge satisfaction and letting them have a break. Where they are weak in the physical world, they can be strong in the virtual world. If you don't want kids to take out their anger in video games, then you better expect them to take it out on real, physical things. If you want kids to vandalise things, then you aren't popular with the owners of said things. But if you manage to introduce these rules, then you should expect many kids, and their unfortunate parents, to hate you for taking one of the places where they feel in control. Sure, they can play other games, but beating someone in a race on Forza doesn't provide the same relief of shooting some unlucky person in the face in Destiny. Just let kids play the game they love, and if you feel as though you don't want to play with kids, then don't. Mute them in chat, create a party or leave the game altogether.
