I think a better parallel would be between Nero and Obama, rather than Caligula and Obama. Caligula was likely insane and a pervert—and he flaunted both traits. I don’t think Obama is either; nor do I think he’s stupid.
I do think that, at his core, he’s a Marxist who hates America and anything he perceives as ‘colonial’. And, to the extent he can get away with it, he’s trying to weaken the Country and remake it in his own image.
Jeremiah Wright was well-known for attracting to his church young, upwardly mobile gay men who he could meld with unattractive but interesting young black women (to provide beards for said young "down low" black men).
It is apparently well-known in Chicago that this was the situation with Obama and Michelle (Wright's program was called, well, "the Program").
Anyone who thinks Obama is a straight male needs to get out more (and not getting out enough ain't a bad thing).;-)
