Black clergy views on the gay marriage issue

When did black civil rights leaders try to compare their movement to the women’s right struggle for support? The subject isn’t who’s more oppressed, it’s about the validity of a comparision between gay rights movement and the black civil rights movement. I don’t really think that it’s that big of a deal, since the black civil rights movement is now an all-purpose omni-example for any type of agenda anyone could ever want to push.
