Just to say that I believe that words are not as important as speech. About a month ago I had an attempted conversation with a player who was eventually muted from the multiplayer lobby because he had been crudely propagandizing Catholicism for weeks. I don't have the screenshots because the day I got into the conversation it ended up resolving and user 1 muted him. But in his case it wasn't so much about the words he used, although he did mention Nazism, talked about blacks in a demeaning way, etc. The point is that he was urging us to read the bible, to thank Jesus Christ, he kept copying phrases from the bible and saying that God created the world, that this game is an ode to Jesus Christ, etc. In this particular case, I do not think that a multiplayer lobby is a place to spam this kind of things and, in addition, if I told him to stop, he started a 1vs1 dialogue in which he was not respecting the freedom of each person to think what he wants. It was like if you get a letter from Jehovah's Witnesses at home and an attempt of absolute indoctrination. I was like "Stop, ok, it's perfect that you believe all of that, but this is not the place to adoctrinate people and everyone has right to their own thoughts". And he was like "You are wrong, you don't know anything because this game is an ode to Jesus Christ and we should thank Jesus Christ because God... blablabla and how can you explain it, and the other thing... You can't, because God... more blablabla"
How do you control that? It wasn't about the words, but it's true that it took me half an afternoon of discussion and other people in the multiplayer lobby intervening and freaking out to get it silenced.
