Decided to take out the personal opinion about a certain individual; however, I'll leave the rest. It's a perspective on a concept.
Personally, I don't get the idea of "royalty". I mean, I understand it perfectly well, but don't get why it has been allowed to persist until now. So called "royals" just descend from someone that was more brutal than someone else that ruled before them, and probably had quite a bit of inbreeding along the way (Habsburgs come to mind - have to keep that "royal" blood pure!). There's just something that seems offensive that someone is inherently better than someone else based upon birth and ancestry. They're no better - just had a head start and lots of ancestral wealth because people decided to deify one of their relatives long ago. I guess, based on the inbred aspect, the US has some royalty, but they live mostly in West Virginia, Alabama and Western Louisiana.
It's just offensive to the American way of thinking that people aren't actually free citizens, but the subjects of a monarch and lesser beings than the "nobles". Some countries say differently in official documents, but in practice and in the way folks revere "royals", they often still act as subjects and rarely push back as "royals", and the government folks they support, chip away at basic rights. They even look at rights differently, thinking they are "given" or "granted" rather than inherently existing. Something "given" or "granted" is a privilege - not a right. A right exists even when it is denied - that's why a bunch of folks signed a certain document on July 4, 1776 and told George III and Parliament to kindly go fuck themselves.
As for the concept of "divine right" or "divine rule" - it was something started by those brutal ancestors in exchange for not looting the churches, or when and where the church held greater sway, as a reward for fealty to Rome. And even with a "king", how united is England and the UK? I could go on, but I won't. Whether you agree with me or not (that's a right everyone has), I think you can at least see the perspective I'm coming from.
