And perhaps I'm old fashioned but I don't see being a politician conferring stature or notoriety. Everything else being equal, Roosevelt's son, or any other politician's child, going to battle is not the same as a monarch's child going to battle.
Are you an American?
I'm not sure you're as old fashioned as you think as you don't exhibit in your views the disdain our founding fathers had for monarchy or privilege gained by birth. The American ethos as I understand it is that we are at birth all equal in the eyes of God and history. In my simple mind the fact that any nationally elected official's son or daughter who went into battle to protect freedom and democracy far exceeds that of a demonstration of commonality exhibited by any monarch's child. I think you need to reconsider what being an American means. Royalty, monarchy, privilege mean nothing....its all about freedom in my humble opinion. My regrets if I interpret your meaning inappropriately.
