Please, since we're not in the States try to use normal political terminology. Your are describing the difference between a constitutional representative democracy and anarchy. The U.S. Canada, Australia, the U.K., etc are constitutional representative democracies, so say so. A republic is simply a form of government that doesn't have a monarch, it has nothing to do with democracy, tyranny or anything else. My advice is expand your political science education beyond sovereign citizen web forums.
