If you reside in the states, check out some reading on the Constitution and the Bill of Rights, some pretty interesting examples of inferred rights, how they've come to be such, and even the laws that have been put into place because of them... Fascinating stuff if you're a history buff.
What we have here in the states is a REPRESENTATIVE democracy. We ELECT people to act on our behalf. Those elected officials make the rules we are governed under, not the hoi polloi.
And as such in this two party system of ours, there is a guarantee that about 50% or so of the population's voice will not be heard, as our process deems it a "winner take all" type of deal for the ruling party.
There is no community rule as you have erroneously stated. It would be chaos if that were how government was run in the US.
As for the mods, they have a stated mission as requested by the site administrator, who is the one who makes the rules, not the community.
No one besides them know what goes on behind the scenes. Frankie B's explanation may have come across as a bit obnoxious, but it's his site. He can do what he wants.
