Was the Experiment in American Democracy about letting the violent minority rule the rest?

In all honesty, yes. The founders didn't want everybody to have equal rights, in spite of what the whitewashed version of History would have you believe. They wanted white male property owners to be able to vote, and nobody else. They didn't even consider black people to be people. But to listen to certain people who worship them, they were perfect and without fail, and we should still honor everything they wanted to do.
