Since the beginning of this century, they have shown NO solidarity with either their own blood relatives (refusing to grant asylum to the Tsar and his family and allowing the Lloyd George government to vilify and encompass the abdication of the Kaiser) or their class (allowing Parliament to install inheritance taxes that have reduced the aristocracy to tenants on their own estates), or -- worst of all -- with their own subjects.
Regal authority comes from God, NOT for the pleasure of the monarch, but for the good of the subjects. The Windsors have de facto abdicated, selling their subjects into slavery under a socialist dictatorship. All the while, Her Majesty and her repulsive brood have been assured that their own income and prerogatives remain intact.
It is people like the "Windsors" who give monarchy a bad name.
I say send them packing and bring back the Stuarts.
