I would say that on a dispassionate and purely scientific/ academic level I am mildly pro-monarchy on the grounds that it generally produces the most peaceful and stable outcomes for the peasants, I mean citizens.
I’m not sayings its a perfect system and i’d be very happy to abolish it if we can come up with a demonstrably superior algorithm, i mean system.
One of the best reasons for having a monarchy, in my view, is that you get a good chuckle at those who get really exercised over the whole thing and turn up to royal occasions to shout things like “NOT MY KING!”. That never fails to put a smile on my face.
