It is a privately owned gaming server. The rules for mumble and the game are, no profanity. If you don't like the rules, then you should look for a place to play where profanity is welcomed, By the way, the majority of the people you listed, though historically significant, were very ill-mannered, often disrespectful of others, as per your description of FDR, innapropriate..... so the answer to your question is...... yes. If you are personally aspiring to be president or a similar important historical figure, I suggest you focus on, and try to emulate, attributes other than profanity. Try doing good rather than bad. You may lilke it.
