Although I suspect you're on the right track, I assume that you are assuming the characteristics of those people and their situations, and only because I have not heard specifics about them. One thing is for sure: the WH ambush tactics the other day were way our of line with any adult behavior while the guest, the President of South Afica conducted himself intelligently, deplomatically, and in a civilized and adult manner.
I hope most white people, like myself, find the US "presidential" behavior abhorrent, if not completely embarassing.
