There’s a false right-wing talking point that the US “is a republic, not a democracy”. The US is both a representative democracy and a republic, but the talking point equivocates on the meaning of “democracy”, conflating it with direct democracy, and this apparently fools far more people than it should.

The goal of people who push such propaganda is to weaken support for, and understanding of, democracy. There isn’t any doubt that they, and the people who unthinkingly repeat the propaganda, are a threat to democracy.
