... my defence is of the monarchy, not the current royal family
I know, Blossom, and though I'm coming at it from the other point of view I actually agree that the whole thing is about the institution rather than individuals, hideous as many of them are (and rightly criticised for it)
I can even go along with the cost/stability concerns, except that first of all nobody suggests doing this overnight - impossible anyway - and that, for me at least, the issue is important enough to be worth the cost
