People keep saying this. It's not necessary to point out the distinction every time someone refers to the US as a democracy. It IS a representative democracy because we choose our representatives democratically. When people refer to it as a democracy, it does not imply that they think it's a direct democracy. Direct democracies are rare.One nation under god. The word Republic falls in there as well. No mention of democracy past the MSM agenda machine.
Although it is correct to call it a democracy, it is not as accurate as calling it a constitutional republic. Calling it a democracy is accurate in a similar way to calling a '57 Chevy Impala a car. It IS a car. The US IS a democracy. It's just more accurate to call it a constitutional republic.
A republic and a democracy are not mutually exclusive.
But, since you bring up the MSM agenda machine. I do suspect there's something else going on when we hear woke people say things like, "They're destroying our democracy!" They have a different sort of definition for democracy than what we think of it. So "true" democracy to woke people is that it can't exist until everyone is equal. And everyone can't be equal until all the institutions are destroyed, and rebuilt from the ground up to be equitable for everyone. Sound Maoist? It's not coincidence. Long story short, "true" democracy can't exist without communism to equalize everything. So it may be the case that she has this definition in mind.
