I have no problem with the Royals as human beings, it's just the concept of monarchy which makes no sense to me.
I agree the concept makes no sense.
However it's the concept that creates a great political tool, national ambassadors who are apolitical.
Also I think there is a great need in people for spiritual totems/figureheads. That while people need the nations leader to make the decisions and run things, they need them for some emotional reasons also. I'm quite comforted that our figureheads or leaders in a more totem sense have no power. That the emotional focus can be directed there and the rational focus can be directed at the people doing the job.
I mean all the countries that have figurehead apolitical monarchies do pretty well in the rankings in terms of freedom, democracy, being liberal etc. Of course it could totally be unconnected.
