Democracy or Republic

I have heard so many times that We ( meaning the United
States) is a Democracy, but I have to differ.
We are not a Democracy, but a Republic.
In the The Pledge we say " And to the REPUBLIC
for which it stands."
So if we were a democracy, we would say
" And to the DEMOCRACY for which it stands."

So I am putting on here a little of the difference between the
two, so here it is or they are:

A Democracy
The chief characteristic and distinguishing feature of a Democracy is: Rule by Omnipotent Majority. In a Democracy, The Individual, and any group of Individuals composing any Minority, have no protection against the unlimited power of The Majority. It is a case of Majority-over-Man.
Democracy, as a form of government, is utterly repugnant to--is the very antithesis of--the traditional American system: that of a Republic, and its underlying philosophy, as expressed in essence in the Declaration of Independence with primary emphasis upon the people’s forming their government so as to permit them to possess only "just powers" (limited powers) in order to make and keep secure the God-given, unalienable rights of each and every Individual and therefore of all groups of Individuals.

A Republic
A Republic, on the other hand, has a very different purpose and an entirely different form, or system, of government. Its purpose is to control The Majority strictly, as well as all others among the people, primarily to protect The Individual’s God-given, unalienable rights and therefore for the protection of the rights of The Minority, of all minorities, and the liberties of people in general. The definition of a Republic is: a constitutionally limited government of the representative type, created by a written Constitution--adopted by the people and changeable (from its original meaning) by them only by its amendment--with its powers divided between three separate Branches: Executive, Legislative and Judicial. Here the term "the people" means, of course, the electorate.
