They might claim that his story is an indictment of the American right, but as you guys have noted with the links, it is in fact an indictment of ultra- liberal parenting (Especially if the ultra- liberals in question are ultra- rich). He clearly spent his entire life being spoiled rotten by his parents, mainly his father, and given every single thing he wanted as a kid (Don't forget, liberal parenting styles are all about imposing no limits on your kids, doing whatever they ask, never employing any kind of discipline, and striking the word "No" from your vocabulary). So, for so many women to turn him down and tell him "No," likely the first people in his life to do so, was something the spoiled little punk was unaccustomed to, and he thus didn't take it well.
His bragging also shows he thought the way to a woman's heart was by impressing them with his money and overpriced possessions. Problem is, most women are not shallow enough to buy into that, especially if he has such a rotten personality behind it.
He's a lesson on why parents shouldn't spoil their kids, because he's the kind of adult they could grow up to become.
The SPLC should blame the Left for his rampage, not the Right.
