Video games should be a neutral place for everyone.
If you don't like what they say then put them on ignore and that's the end of it.
I'm not a supporter of racism or slurs or anything of the sort, but I do believe in freedom of speech especially as an anonymous person in a video game.
Stop trying to control other people through your victim mentality.
No one forces you to play this game.
**Everyone should be able to say whatever they want whether you like it or not. **
Edit:
As an additional point, once you start deciding what is okay to say and what isn't, it becomes impossible to draw the line. If this continues, a snowball effect will emerge and this will get way out of hand and ruin this amazing game.
You know why WoW died? It listened to all the cries of the forums. Slowly it became a socialist game where everyone got everything they wanted. Everyone had the same gear, every class could do everything, everyone was exactly the same. Then everyone hated it and quit.
In league the number one cry isn't balance, its what players can say to one another. So just use your imagination on where this will lead.
