According to my dictionary, the primary meaning of democracy is:
"a system of government by the whole population or all the eligible members of a state, typically through elected representatives:"
The United States fits that description. So it's a democracy.
Our nation's founders are rolling in their graves.
Here are some examples of how they described Democracy:
"Democracies have ever been spectacles of turbulence and contention; have ever been found incompatible with personal security, or the rights of property; have in general been as short in their lives as they are violent in their deaths." --James Madison (You know...that guy who wrote our Constitution), Federalist Papers (# 10)
"When the people find that they can vote themselves money, that will herald the end of the republic." --Benjamin Franklin
"Remember, democracy never lasts long. It soon wastes, exhausts, and murders itself. There never was a democracy yet that did not commit suicide". --John Adams
"A democracy is nothing more than mob rule, where fifty-one percent of the people may take away the rights of the other forty-nine." --Thomas Jefferson
"Democracy is the most vile form of government... democracies have ever been spectacles of turbulence and contention: have ever been found incompatible with personal security or the rights of property: and have in general been as short in their lives as they have been violent in their deaths." --James Madison
"This was the only defence agst. the inconveniencies of democracy consistent with the democratic form of Govt. All civilized Societies would be divided into different Sects, Factions, & interests, as they happened to consist of rich & poor, debtors & creditors, the landed, the manufacturing, the commercial interests, the inhabitants of this district or that district, the followers of this political leader or that political leader, the disciples of this religious Sect or that religious Sect. In all cases where a majority are united by a common interest or passion, the rights of the minority are in danger. What motives are to restrain them?" -- James Madison
"It has been observed that a pure democracy if it were practicable would be the most perfect government. Experience has proved that no position is more false than this. The ancient democracies in which the people themselves deliberated never possessed one good feature of government. Their very character was tyranny; their figure deformity." -- Alexander Hamilton
"In a democracy, the majority of the citizens is capable of exercising the most cruel oppressions upon the minority." --Edmund Burke
