Evidence of their arrogance? Oh, I don't know, how about the fact that they've set up an entire set of special rules and protocols for meeting them that they still expect people of ACTUAL accomplishment to observe? That's pretty arrogant. And besides, the entire NOTION of royalty is that their BLOOD makes them special. What other evidence do you need? The fact that a democracy of any kind can continue to support such a notion is baffling to me.
And you're completely mis-stating my position. If I actually held the position that you claim I do, you'd be correct to refute me.
My position is this: Their position in society, their job, their role that dictates 90% of their behavior is based entirely on the actions of their genocidal ancestors. Suggesting that all wealthy white people in the Southern US are descended from slave owners is not only untrue (the population in the US is much more mobile, both in terms of geography and demographics than you're suggesting), but a poor comparison even if it were true. There isn't an entire publicly-funded institution dedicated to celebrating how awesome slavery was, so... NOT THE SAME THING. The descendants of slave owners don't inhabit areas where they still have slaves so that people can come and ooh and ahh, so... NOT THE SAME THING. The descendants of slave owners don't insist that all black people address them as "master", so... NOT THE SAME THING.
People can and have renounced their royal positions, so any difficulty royals experience as a result of their position (boo hoo hoo) once they reach the age of accountability is COMPLETELY self-inflicted because of a wish to retain their status and wealth.
I don't "hate them because of the actions of their ancestors". I hate the institution of which they are a part. Because they have chosen not to renounce it, I judge them for participating in it. I don't hate them at all, and certainly not for their ancestors' actions. I judge them for their own.
