[E. Pluribus Unum]

Democracy, otherwise known as "majority rule," is two wolves and a sheep voting on what to have for dinner.

That is why the United States is a "representative republic" rather than a democracy.

[Laissez-faire capitalist]

Yes, we are a Representative Republic, but our Representatives, when voting on any matter, at either the state or federal level, engage in majority rule whenever they vote on something.

As well, the courts are majority rule.

As well, "We the People" have the right Constitutionally to demand a Constitutional Amendment from our Representatives, banning same-sex marriage, etc... This is our Constitutional right and was placed within the Constitution by the Founding Fathers.

"We the People" can, from time-to-time, engage in our own majority rule when we see fit through a Constitutional Amendment. It's called people power.

Furthermore, there is nothing within the Constitution prohibiting an Amendment to the Constitution which would allow the voters of each state to vote on same-sex marriage, abortion, etc...
