Re: Royal highness
Personally in terms of rights I dont believe the current Royal Fammily of England (Great Britian) has any right over the people they claim to rule. Going by Divine rights here the true titular Rulers of England should be the Anglo Saxon decendents of Wessex have long since vanished into the mists of History. The current Royal Fammily are also of Germanic origin I believe they are from the house of Sax-Wiemar? 
Anyway they are Cousins of the German Kaisers and co… and frankly like me they are outsiders to the British Isles. 
If it was up to me the Crown would belong to whevero worked most hard for it…
