Maybe you should ask for clarification before you rip on someone. It helps.
But I will do my best to explain it to you. A democraTIC government encompasses any government in which people legitimately choose who governs them, and includes Parliamentary Constitutional Monarchies (such as the UK), Republics (such as the US, germany and Brazil) and direct democracies, like the Swiss cantons of of Appenzell Innerrhoden and Glarus. That last example is democraCY, wherein all eligible citizens directly vote each time a new law is proposed. The majority wins. This is often called "tyranny of the majority" and is nearly as bad (if not worse) as dictatorship.
The United States, while it is a democraTIC country, is not a democraCY.
It's subtle, but there's a difference.
