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

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.

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.

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

For those who were actually old enough to have experienced the 1970s and not for those who were born in the 70s. What were the pros and cons of that era?

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

—Thomas Jefferson

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.

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.”

Why? Try these on for size:

Are there any nude pictures of women with big tits?

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

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

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.

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

—Benjamin Franklin

What can I do after 18 cops raided my home, without a warrant, seeking a person who didn't live there and wasn't there, and also went through all of my stuff? The person wasn't on the lease, and they didn't see him enter.
