The VAWA is being held back for several stated reasons that Adam Serwer explains. Teh gayz are of course one of them:
LGBT rights: Republicans agree that organizations receiving federal grants shouldn’t discriminate against people on the basis of sexual orientation. They just don’t understand why Democrats want to make it the law.
“I agree that shelters and other grant recipients should provide services equally to everyone,” said Grassley. “But advocates of this provision haven’t produced data that shelters have refused to provide services for these reasons.” He added that the nondiscrimination provisions were “a political statement that shouldn’t be made on a bill that is designed to address actual needs of victims.”
The underlying, unstated reason, though, is that Republicans don’t see domestic violence as all that important of an issue.
