Fair point, up to a point. And you could say the same about the French Revolution (which people seem to ignore was followed by The Terror, and much more).
You can't unilaterally remove the Royals without consensus, as that would be an imposition, just as much as all this nauseating compulsory mourning. And to do so, history tells us, would lead to extended periods of political violence.
Power vacuums and power struggles tend to be very ugly.
That said it's good to have this forum, for instance, to find out that there are plenty of people who also find the bowing and scraping so utterly degrading.
Anyway, time and history will move on.
I've just seen the headline, King Charles to meet Prime Minister Liz Truss. That says a lot about the State we're in.
I hope someone somehow can build something out of the rubble and the ashes. I'd like young people to have a future.
