Joseph, Firstly, you can make the argument and some still believe it is possible, Read about the town of Orania and the Volkstaat. However, I shudder to think how Jews would fare under that model.
Secondly, I did say she is the moral example. I don’t know how Charles will look when he ascends the throne. He’s been good the last few years. People are looking forward to William’s eventual reign, as thus far he hasn’t got that baggage. People like and respect William & Kate as the future of the monarchy.
