FYI, I hate royalty and would gladly get rid of it.
I wasn't comparing Diana to JFK on the level of which one deserved power or respect. I was only using them both as popular (not necessarily with me!), famous figures who died very publicly in cars.
I assumed the point of posting that photo was, "Oh look, your British cared about someone and then they died! Har har har!" Why else would you use that picture? If your point was just that we have some unelected people with power then that was a really stupid picture to use. If you'd instead posted a picture of the queen or Prince Charles I might have actually agreed with you. But I still would have pointed out all the unelected and undeserving people with power within the USA.
That's your problem: You can't see that everything you use to criticise other countries applies just as much to your own. You're blind to your own country's flaws while you revel in the flaws of others thinking they make you superior. Ignorant idiot.
