Hmm. Well, here's how I see it.
First off, the American ideal is not democracy, it's a constitutional representative republic, finding its fullest and best to date design and expression in the American School of economics. This is a highly intelligent, nuanced, idealistic-yet-realistic view. It is most definitely not democratic, at all. If you want to talk "historical fact", then name me ONE democracy in ALL of history. You can not find one. They don't exist. Democracy is always a lie, a con, a swindle, a manipulating the masses into thinking they have self-rule.
Second, there's nothing dangerous about denying democracy. It's called sanity. If someone says "the aliens are coming to kill us" yet there is ZERO evidence for their claim, I deny it. It's a healthy thing to do. The same goes for "democracy", "libertarianism", "communism", etc. -- all synthetic ideas and demagoguery designed to get people to cut their own throats.
Third, there is most definitely blood on the sword of America. The Revolutionary War, the Civil War...
Fourth, Plato himself forthrightly speaks out against democracy. He states: "These will be some of the features of democracy... it will be, in all likelihood, an agreeable, lawless, parti-colored society, dealing with all alike on a footing of equality, whether they be really equal or not."
