I just don't see your point, what actually is it? The Royal Family reprisents tradition, and gives our country some national identity, they are a great international embassidor, I find it quite funny that Kiwi's love the Queen, as do most Aussies I know, and the Queens face is on their money.
Yeah there has been some embarrassments, in the shape of Phillip, but Tony Blair (The man who wanted to be head state) did many, many more..
