I'm writing here as one who is not a monarchist nor a theist, and who is in principle opposed to having an established church. I would also like to make it clear that I am not, and never have been, an adherent of the cult of Diana, though beyond that I do not intend to go. So, on that basis…
Oh, please! Give Charles a break. His mother has barely been buried, and after all those frustrating years of being on standby to take over her job he's now in it up to his eyeballs. If he, many years ago now, sought comfort in the arms of the woman he had always loved and who understood him in ways that his own father, a "man's man" as a military one-time bf of mine who met him said, did not. It's not like he's been a reckless rake, carousing around the city in the small hours of the morning. He has some funny views on some things, and some sound views on others, and he may not be the sharpest knife in the drawer, but he's always been a gentle and thoughtful man, kit seems to me. As a person I rather like him. Consider some of his predecessors who have held the role of head of the Church of England: Edward VII was hardly an angel. George IV? <splutter>!
As a wise man didn't quite say once, "let she who is without sin cast the first stone".
