Actually, a democracy is where each person votes on each issue, therefore, you cannot have a representative democracy. The two words have separate meanings. Democracy means that each person votes on each issue. Representative means that they vote someone in to vote for them. They do not go with each other. You cannot do both.
Yes, it's a distrust of pure democracy, because we don't have a pure democracy. The Senators were originally supposed to be elected by the state governments, with the lower house elected by the people. It's called checks and balances.
Actually you can have a REPRESENTATIVE DEMOCRACY --- that is what we have in America .. in Great Britain .. the concept has been around for over a couple thousand years. That is basic civics that I taught to 7th
through 12 graders.
Ancient Athens tried "pure democracy" and it lasted about a generation ... and even then only "citizens"
were allowed to vote (not women, not slaves, not indenture servants).
The indirect election of Senators by the state legislatures .. is exactly what I was talking about in my
previous posts -- but that is not "checks and balances" -- that is an example of states' rights in relation
to the federal government and of REPRESENTATIVE DEMOCRACY.
Checks and Balances is the concept of the Executive, Legislative and Judicial branches having certain
overlapping powers ----- for example - the President negotiates treaties with foreign governments BUT
the US Senate must ratify (approve) the treaty before it take effect.
Another example -- Congress passes laws - the President can sign it or veto it -- and the Courts can
interpret and/or declare it unconstitutional.
