I do not think that the monarchy hasn't lasted 1000 years is a reason for this circus to carry on.
I am a near contemporary of Diana, so I am very conscious of the years of life she has lost largely due to being part of the RF and the monarchy....the fact she hasn't seen her sons grow up & marry, has never known her grandchildren. At the time of her wedding I was quite an ardent monarchist and celebrated alongside many millions of people, that very lavish and taxpayer-expensive wedding of the century which we were invited to believe was a love match.
It has since emerged that the wedding & marriage was a hollow farce all along, and other revelations over the years have shown the extent to which the RF lie and manipulate their images....hide the extent and sources of their wealth from the public, cover up misconduct and even crimes committed by their members.
And that is before we even get on to the anti-democratic nature of the institution itself. Do Charles, his son & his son's son even want to take over? We don't know and it seems they don't get a say.....the treatment of Diana, Harry, Meghan etc shows what will happen to them if they dare to fall out of line.
The Monarchy lost my support years ago & I am staying lost. And I am not alone.
