I prefer a community where everyone is free to say what they want without risk of being censored.

Do you, actually? If you joined a book club in the real world, for instance, and everyone around you was constantly going on about the Jewish problem and why slavery really wasn't that bad and why women are useless for anything but housework, would that be a place where you want to spend your time? Would you be a coward with fragile beliefs if you decided to go somewhere else? Would it be horrendous censorship if you wanted rules for basic respect and decorum as generally exist in normal society? If someone followed you around all day constantly challenging every thing you ever said, would you really not find that at least mildly annoying?

Just because one might not want it to be illegal to state opinions, that doesn't mean that people can't appreciate at least some common understanding of a space's purpose and rules for discourse. Real wold communities almost never allow unlimited speech, because that can get extremely disruptive very quickly. I don't understand why people think that online spaces must be so radically different.
