There should be a new word--"retardacruel". When someone's being not just turdballs retarded in their wacked-out beliefs, but also willing to exert a level of cruelty on others in the furtherance of their wacked-out beliefs.
I bring you Exhibit A, from Mississippi, a state that brought us great things like Jerry Rice, David Ruffin and William Faulkner (full disclosure--I never read any Faulkner), and on the other hand also was the setting for a lot of hangings of people whose mistake was being born black. (Or, being born black and making the mistake of thinking they could vote or be served in diners). Apparently, there was going to be a prom, two lesbians wanted to attend together with one wearing a tux, and the school system said there was a rule that all prom dates had to be of the opposite sex. The lesbian girls got the ACLU involved, and the school cancelled the prom rather than bend their rule.
The thing about this is that yes, I get that some people don't like homosexuality. They don't want gays to marry, teach in schools (if they're openly gay, which of course means that secret gays will teach your kids! OOoohh), or adopt. I can disagree with that, as I disagree with unions and IRS rules. But it really crosses the line when they can't let two girls just attend a freaking dance together. Worse, by cancelling the event, they're now making those girls outcasts as other kids in the school are going to blame them for ruining the prom.
Why not just say to objecting parents "hey, it's a dance--no one's supposed to be getting their screw on at the dance, gays and straights included. They're just going to dance to crappy music, get their photos taken, and eat some overpriced food. Then they're going to be out of our jurisdiction and probably hit some motel and lose their virginity if they still have it. You might want to keep an eye on your own kids, since those little monsters are probably going to be laced with STDs for a while after that. If they want to attend the dance with someone of the same gender, who cares???"
Appaently it's easier to wreck some kid's social life to take a stand on principle. Especially if that principle is "we hate the gays so much we're willing to ruin a prom over it."
