Constance McMillen wanted to attend prom with her tuxedo-wearing girlfriend. Itawamba County School District in Mississippi (hey, this is the state that didn't ratify the 13th amendment abolishing slavery until 1995, yo) was all "oh noes, the gays" and "oh noes, girls wearing tuxedos!" and banned the young woman and her date from the prom, then canceled it for good measure.
She took it to court because hey, you asshats, her civil rights were violated. A federal judge agreed but isn't requiring the school district to reinstate the canceled prom because a private event is being scheduled by parents who, unlike the school district, have somehow managed to make it to the 21st century a smidgen enlightened.
There is no valid argument against lesbians and gays attending prom. None.
There is no valid argument against women wearing tuxedos. None.
This is a bunch of misogynistic, homophobic tripe.
It is embarrassing.
