Why is the word "democracy" not in the preamble of the US Constitution?

To blacks: “You can’t drink from that water fountain… eat in this cafeteria… ride this bus… go to this school. We voted fair and square and your side lost.

—John Adams

To slaves: “You can forget your notions of freedom. We voted fair and square and your side lost.”

Why did my ex of 2 years move on so fast after he left me? Why does he act so cold towards me, and as if I don't exist?

Another tendency, which is extremely natural to democratic nations and extremely dangerous, is that which leads them to despise and undervalue the rights of private persons.

I do not say that democracy has been more pernicious on the whole, and in the long run, than monarchy or aristocracy. Democracy has never been and never can be so durable as aristocracy or monarchy; but while it lasts, it is more bloody than either.

When the people find they can vote themselves money, that will herald the end of the republic.

In other words, our Founding Fathers and other Whig intellects of that time well understood that democratic methods are the surefire means to do serious damage to the rights guaranteed under republican self-government.

Why? Try these on for size:

How did Farrah Fawcett die?

[with republicanism being the rights-protecting form of governance afforded us by our Constitution]

To Indians: “Pack up what belongings you can carry and start walking to Oklahoma. Your fertile lands are ours now. We voted fair and square and your side lost.”

Meanwhile, when the Democratic Party formed in 1828, it was with a Tory outlook keen on robbing others of their rights:

What's the most trivial thing that ever made you go to the doctor?

The republican is the only form of government which is not eternally at open or secret war with the rights of mankind.

Majority-rules democracy is the way that majorities run roughshod over minorities, destroying rights and all ideas of equality under the law. No fair-minded person wants anything to do with democracy.

—Thomas Jefferson

Is it possible for buyers to negotiate after an inspection if the appraisal is lower than expected?

—Alexis de Tocqueville
