Constitutional democracy only works if the whole population agrees to the moral and practical superiority of freedom of choice and equality of opportunity. And then it is allowed to function. It doesn't happen naturally without conscious human intervention.
Naturally, if society was a crude free-for-all, we'd have things that resemble Somalia, or the Mexican drug cartels, or North Korea (along with things like The United States). In these examples of political structures, we have the most powerful taking control of whatever they can take control of. Then they hold it there with whatever means they can for as long as they can.
Democracy is like this but all the people say "hey, let's try giving everyone the same amount of power so we can normalize this game called life and control this experiment for longer-term goals."
Basically I'm saying that power supersedes even democracy oh the moral pyramid. There is one level even beyond democracy and here you'll find it in the company of authoritarianism, communism, etc. Power is at the top level of this pyramid. It is based on survival of the fittest. Power is the only universal moral because it is a fundamental law of nature. Democracy is not a fundamental law of nature. It is a construct of a specific subgroup of humans. It was conceived and designed to achieve a specific goal. And because there is a goal, and all goals are different, it is a subjective end. Therefore democracy is arbitrary and subjective—not a universal moral.
As much as you'd like to believe in inalienable rights, if I have a gun to your head, you can bet I can alienate your "natural" rights. Yes, you'll always have the choice of death or obedience, but once you're dead, you're irrelevant. But if you have a bigger gun, then I can no longer "alienate" your rights! You can "alienate" mine! That's power. Democracy is abstracted into laws which are ultimately enforced with power (guns, police... head) Because of this, democracy is not fundamental. It is human-designed construct and therefore it is not a universal thing.
Another way to think of it is like this: we have a 10 x 10 grid and we have 100 people. Democracy assigns each person a square. Power lets people take whatever squares they can defend. The end result of these two philosophies will look different, but democracy was specifically designed to artificially treat each person as equal so we can achieve the end goal of giving people a chance to succeed. Supposedly this will help society be better off, but this goal is still an arbitrary goal (though most people would agree on this) and democracy is just the means. The natural outcome is to give spaces to those who can defend it. If you can't defend the space, you don't deserve to own it. Democracy is human manipulation of this system to try to achieve better results.
I will fully disclose that I am a firm supporter of democracy (because of the way it normalizes society), but I want to make it clear that it's because it's the best method so far, not because it's inherently right.
