I'll give you an example of the evils of democracy that has nothing to do with race.
In a civil action in Florida (I forget some of the details), a man was being sued for allegedly stealing electricity from a utility company by winding copper wire loops inside his home and running lights and small electrical appliances from the unmetered current induced from the electric fields of nearby high-tension wires. The man argued that the utility company had no right to trespass on his property with their radiations, which besides might be harmful to his health and to the health of his family.
The judge swept away the defendant's reasonable arguments with an airy wave of a judicial broom and decided that the only "rights" that were violated were those of the plaintiff. The defendant was allowed to speak in court, but he was not able to make the judge behave as though he had said anything important. The case was decided in the utility company's favor, and the defendant was declared to be a common thief, without honor, the fitting subject for public contempt, etc., and was ordered to pay restitution.
One might imagine that the poor man suddenly felt as though he had failed to escape from behind enemy lines and had become a prisoner of war. That's the feeling that you get when your faith in government is dispelled by a raw dose of governmental injustice. That's the feeling that you get when you suddenly sense that you are perhaps six feet or six seconds away from being the target of a policeman's gun, even though you had only sought to have the rights, which you've always been assured that you possessed, recognized and respected. You resolve never to rely on any public institution to do right by you, ever again, for as long as you live.
Isn't it obvious that his "theft" of electricity was merely a partial compensation for the trespass of the utility company? If I must allow gas company trucks an easement across my land, then must I also let them use my horse pasture as a storage depot for their not-quite-empty propane tanks? And, if they dump their not-quite-empty propane tanks in my horse pasture, and I siphon away the last of the fumes in them, then which of us, me or the utility company, has offended the other's rights the more? What's this? The utility company can impose on my property rights by littering my land, but I can't impose on their property rights by removing a usable portion of the litter?
My comparison might not be perfect, but it's good enough to show that the judge in the case was minded to protect only the property rights of the electric utility, and any rights that the defendant had were disparaged and denied. Why did the judge have this attitude? The answer is that state judges are elected, and in order to win elections a lot of money is required. Utility companies are better sources of campaign contributions than little old homesteaders. In a democracy, you get all the justice that you can pay for, but typically not one scrap more. (And the prices are high.) However well a Constitution might at first have secured the basic rights of the citizen, this security will erode as democratic workings cause the careers of elected judges and other officials to depend on pleasing those who can most generously finance election campaigns.
The only difference between a civil democracy and a "banana republic" is time. Enlightened standards for the conduct of public affairs are intrinically noble things. Justice is incompatible with mob rule. Someone who can influence the way the mob votes, which is basically what campaign contributions do by way of buying propaganda, can motivate a judge to do him improper favors. If this judge is some kind of honorable jackass who doesn't do improper favors, then come the next election a more pliable judge will ascend the bench. Being dependent on the democratic process will corrupt anyone, sooner or later, even if he begins his career with the best intentions. Democracy has the worst of political filtration processes: it eventually puts the worst men into the highest offices.
I doubt whether there is even one county courthouse in America that hasn't become a cesspit of corruption. Democracy is not something that you want to have your nose rubbed in. It stinks.
