Salon interviewed author Richard Rodriguez about Proposition 8, among other topics.
He offers a different take on why the church continues to oppose gay marriage:
As the American family fractures and the majority of women choose to live without men, churches are losing their grip on power and scapegoating gays and lesbians for their failures.
…
The possibility that a whole new generation of American males is being raised by women without men is very challenging for the churches. I think they want to reassert some sort of male authority over the order of things. I think the pro-Proposition 8 movement was really galvanized by an insecurity that churches are feeling now with the rise of women.
I still believe the Christian Church will get over this. As a new generation of leaders takes over, the Church will become less homophobic. It’ll take time, but most younger Christians don’t see any contradiction between what the Bible says and same-sex marriage. They support marriage, period.
