Holy shit. Let me teach you.

A democracy is where people are allowed to vote for government leaders.

A direct democracy is where they vote on issues directly. No country has a direct democracy.

A representative democracy is where people vote for representatives who vote on things. Every democracy in the world is a democracy.

A republic is a country that doesn't have a king or a queeen. In other words, they are not a republic - they are a monarchy.

China is not a democracy, but it is a republic.

The UK is a democracy, but it is not a republic. It is a monarcy.

You finally explained to me why so many Americans keep saying "America is not not a democracy. It is a Republic."

I suggest you go back to school.
