Expelled for Having Gay Parents?

What the hell? In a country where it's against the law to discriminate against gays, a school has the audacity to expel a CHILD because her PARENTS are gay? Jeeze! Are they TRYING to "goose" the anti- or pro-gay folks into a fight? Do they WANT to have trouble with the feds? Some imbecile in the school office must have SOME kind of an "axe to grind," but for the life of me I can't figure out what it is. I don't have anything against gays, nor do I think they should be allowed to "throw it in my face" and teach my children that "gay is okay." But to expel a CHILD because her PARENTS are gay? How stupid is that? Sheesh!
