Monarchies are for the fools and the sheep to worship. While many have fallen and been replaced by brutal governments, many of those brutal governments were replaced by far better ones, superior to "government by birthright" monarchies and the immediate successor governments.
Tis a fool who would choose to follow a king simply for them being born, true men, always prefer choice, cowards and scoundrals run from it towards servatitude to crowns.
To spread true liberty and give man a choice in his own destinity, crowns should be abolished.
The crown is the enemy of liberty. Look at the monarchies of the middle east, they to shall fall one day, and when democracy spreads through that region, they, along with the civilized world, will wonder why such a primitive system of government lasted this long into modern day civilization.
Whether you realize it or not, in your contempt for monarchy (which goes beyond the position of the more sensible American founders), you are essentially a leftist and no better than the Jacobin thugs of the French Revolution. I have nothing more to say to you.
