it's not supposed to be a "democracy". it was never intended to be a democracy. when it was established, it was established as a representative republic
A "representative republic" IS a democracy. But you're wrong, because:
because only landed white male gentry were supposed to vote and run things.
That makes it NOT representative, and therefore not a democracy.
it also isn't a democracy because that same white male landed gentry protected the minority from a tyranny of the majority.
Obviously not -- I would call slavery oppression of a minority, wouldn't you? And how about the Trail of Tears?
When I say we're supposed to be a democracy, I mean now, not in 1789. The Constitution has been amended to make the system more democratic, and all states have dropped the property qualifications for voting; also, racial and gender bars to voting are now illegal.
We are supposed to be a (representative) democracy. Or in other words, a democratic republic.
