The real issue is surely not whether the monarchy as it is at the moment is ok? Liz and family doing their duty in WW2, steadying influence in turbulent times, tourist assets and some light comic relief from Phil-the-Greek... Patrician but tactful with a sense of where the line is...
Isn't the issue what we are going to have when the next wave comes through...? And it makes you see why Liz hangs in there.
Charles is a well-intentioned nincompoop. He misunderstands love, science, evidence and his role. In another era he should have been shipped off to govern some faraway minor colony. His children were produced with a troubled, beautiful woman he didn't love, who despite her advantages failed all her O levels, twice. His attempts to interfere with Government are well documented. He has not dealt well with people who have pointed out the stupidity of some of his beliefs.
AA grossly overstates things by calling this oppression. I'd me more worried by the CofE links to the Establishment and government TBH. BUT it is telling that no one in this thread has really effectively answered his point about the Letters.
Getting back to the OP, if the Monarchy actually skipped a generation and went to Wills & Kate, a bloke who seems bright, decent and is actually doing a proper job in the forces and to keep his mouth shut, and a girl who seems nice, managed to get to university and do a proper job afterwards, then I'd probably be ok with that.
I'm still not sure why we need a monarchy at all though
