I do understand that some people may be against this, since people may be talking about it normally and maturely.
However, everyone has to admit that Minecraft is not the place to talk about this. I do not want to discriminate people who are affected by those diseases / disabilities, but I do think that it's best to remove it from the filter. For one, 80% of the times it is used, it'll be in a negative way to insult and harm someone else. This is what we are trying to keep from happening, so the other possible uses could be to say that you are affected by it, or a debate about it. I think we can all agree that, as I previously mentioned, a debate about diseases / disabilities does not belong to a Minecraft server, and should rather be carried out in private, so nobody can bring any harmful comments into the conversation. Lastly, no matter how severe, I think it is never the time to declare that one is affected by said disability on a server such as CubeCraftGames. I have all the respect for people who'd like to tell their friends something so personal and painful, however a public chat just bring too many ways in which negativity could be brought upon said person.
That said, I feel like it is a good idea to be adding those words to the filter, not to discriminate the affected, but to simply keep the chat safe, and protect anyone from harm in that direction.
