I would defend an (eviscerated) monarchy such as Canadians like me and other Commonwealthers have as being a social good, insofar as it's a rich & elegant tradition that's not very pernicious.

Actual "off with his head" monarchy... nah.

And if Prince Charles decides to flap his unelected gums too much when he accedes, you may see me change my tune. But at the moment I'm happy to be a subject of HM Queen Elizabeth.
