Is thinking things through your definition of lazy, Dumpy? I've repeatedly said I am not married to the idea that we must have a monarch but that I don't believe in change without benefit and challenged you to show me the goods... which you have steadfastly refused or been unable to do.
And yes the Monarchy, as it applies to Canadian politics IS a check on our democracy, perhaps moreso than the courts, who are also supposed to function in that role (in terms of interpreting the constitution validity of law), but whose members are APPOINTED by sitting gov'ts. Where the Monarchy is pretty much apolitical, the courts are made up of those who have at least made an effort to stay on the good side of their political masters. Or would you like to see us elect judges and senators as well?
And yes, keeping the Monarchy IS cheaper than replacing it would be. You can go back to watching Sesame Street now...
