That's because you're talking about "rights" not "morals".
I have the right to call you an asshole but it wouldn't be moral. Mods have the right to ban everyone with ideas they don't like but it wouldn't be moral.
You do have the right to demand something from someone for free. You do have the right to go to every store in the city and empty every "take a penny leave a penny" tray. But having the right to do it and it being moral are very, very different things.
