I really don't know what you are on about, it reads like you have a chip on your shoulder, perhaps because you were not born into anything.
I am not particularly a monarchist, but I support anything that made GB/UK great, centuries of turning a small union country into something the world knows about, our history.
Sadly, there have always been UK folk who are against anything in the UK, even its history, and want to change it for something like the USSR, China, whatever.
A King or Queen represents our history, is an Ambassador that the world respects, and so does the majority of the UK.
If you don't like the Kingdom, then I am sure there are countries out there that will take you in with open arms, but no, you would not want to lose what your Kingdom does and has done for you......????
But chin-up, have fun on Megan & Harry's fan club, eh....
