Absolutely don’t care. I am not French; I am simply a monarchist. I believe that any nation will benefit once it establishes a monarchy, if it can. We, for example, cannot, — in the foreseeable future that is. But some nations have living royals that could step up.
Well, of the three I would not think the Bonaparts have any claim at all, — for them the title comes from a revolutionary usurper of power. But it is for the French to choose.
Go back far enough and every monarchy started with a revolutionary usurper. In France, both the legitimists and the Orelanists (dubiously) claim descent from Charlemagne. But Charlemagne’s own family were usurpers - aides to the Merovingian dynasty they usurped. Go back in any line and you’ll see thugs with clubs, not any kind of enlightened rule. I’m having trouble seeing a principle other than “it was a long time ago” that makes dynastic thuggery by one family ok, but wrong when done by say, the Clintons.
