Keep in mind that in the USA we do not live in a democracy, We live in a representative republic. We push the concept of democracy to help free other countries from dictatorships, but we do not practice democracy ourselves.
In a pure democracy, the majority always determines the laws, taxes and rules. We elect public officials (representatives) who frequently ignore the wishes of the people to further their own goals or the goals of their political party. They therefore do not represent the people.
If we lived in a democracy, the people would elect the President, rather than the electoral college.
If we lived in a democracy, Obamacare would not have passed.
"Democracy is two wolves and a lamb voting on what to have for lunch. Liberty is a well-armed lamb contesting the vote." -- Benjamin Franklin
