"These black pastors understand that collapse of family, out of wedlock births, single parent households, promiscuity, drugs and crime are the crises undermining black physical and economic health today."
This is spot-on, though legalizing same-sex marriage has nothing to do with any of these. Promiscuity is the leading source of HIV infections, and it is a terrible problem in every community. There is nothing dangerous or "wrong" about being Gay, but there are many dangers in promiscuity, regardless of who you are or who you like. Saying that Gay people are horrible because of promiscuity is the same as saying that all Black people are lazy because the poverty rate for Black people is higher than that for White people.
