"The point is that it shoots down the idea that the players had an itch for "ugly black hookers"
First, if they had an itch for gang raping a black woman, it doesn't follow they prefer black strippers over white ones. Consider the example of Hugh Grant. He was engaged to a young, gorgeous white girl. But when he had an opportunity to get a BJ from a cheap, UGLY, much older black hooker, he went for it. In the aftermath, after his fiance broke off the engagement (surprise), he didn't say "Hey, I've discovered I prefer older UGLY black girls" and start dating one.
Second, lots of chemical reactions take place only when the temperature rises above a critical threshold. It's much more likely that they started feeling an itch after they started drinking and she started dancing as opposed to feeling an itch well before the party began and in the sober light of day. People do things when they're drunk and horny and in a group that they'd never do otherwise. Underage drinking at a "frat" type party with strippers is a lighted Bunsen Burner.
So they request white dancers, and in less than 15 minutes, Reade gets the itch to do an "ugly black hooker" (again, your phrase). In the meantime, he calls his girlfriend, a cab, and is out the door around 12:15 AM. On top of that, the cab driver reported a normal demeanor on Reade's part. Your scenario is nonsense.
I never dreamed that Hugh Grant would be held up as the example of how men act. If Hugh Grant was caught with a "ugly black hooker", than of course these boys would rape the stripper...man, why didn't I see this before? Silly me, I was looking at timelines, lack of evidence etc and the answer was right there....Hugh Grant!
So Hugh's fiance wouldn't give him a BJ. He goes out and buys one from a pro. No big mystery. No secret liking of dirty black women. He just wanted a nice BJ and couldn't get one at home.
Things aren't necessarily that deep you know.
