Meh, who the **** cares. The system of royalty is stupid AF.
Having a symbolic monarch to embody the "mysticism" of the "national spirit" (or to provide fodder for the tabloids) helps deflect that kind of romanticism away from elected officials,
who are then seen more as what they are -- civil servants, magistrates in charge of administration and policy, not a personification of the nation.
The small 'r' republican in me definitely does not like such a vestigial institution as the monarchy, but it is hard to argue it does not have practical benefits for the nations that have constitutional monarchies. A lot of our problems come from our desire to invest our definitions of morality or patriotic sentimentality into legislation and administration because we have nowhere else for it to go, and trying to make the necessarily messy business of politics into Camelot...
Well, it never goes well, and it is usually fake. All-American war hero good Catholic boy JFK was supposed to be the manly avatar of a new generation, but he was really a drug addict who cheated on Jackie almost daily.
Godspeed, Prince Philip. Most of all for your service in the great and terrible WWII.
