I don’t agree with every one of his constructions here, as he seems to be talking from the standpoint of “what’s a greater sin? Homosexuality or X?”, but his general point is solid and powerful:

When I told a religious friend about being inspired by Rosie [O'Donnell] adopting four children, he said to me, “How sad that these kids are never going to have a father.” Lost on him was the irony that without Rosie they would not have a mother either.

Now, Rosie has a media microphone and can fend for herself. But I think about all the other gay adoptive parents who are under assault as being ill-equipped to adopt. We’ve heard all the arguments. Gay parents who adopt will make their children gay (offensive and stupid). Every child deserves a mother and a father (I addressed this above). Gay is an abomination, to which I would respond that leaving a child to grow up in an orphanage where nobody wants them might be an even greater act of sacrilege.

But to my fellow straight people I offer the following challenge. You have every right to oppose gay marriage. It’s a free country. We don’t suppress opinions. But aren’t you under a moral obligation to adopt the children in their stead? Surely leaving kids to drown without love is deeply immoral. But to stop others from rescuing them is an abomination.

A few years ago on my radio show I interviewed two gay men who were in court fighting the government of Florida — my home state, where gay adoption is prohibited — to adopt a five-year-old African-American child who was mentally-handicapped. They had been picking the boy up from an orphanage every Sunday for about a year and now wanted to adopt him. One of the men said, “Nobody wants him. But we want him.” I choked up. The show went to dead air. I could not speak or respond. “Nobody wants him. But we want him.” Here was a child whose skin color for some was all wrong and whose intelligence did not always match up. But to these two men the boy was perfect.

That some would prefer that unwanted children remain in orphanages rather than in warm and welcoming homes is a sad commentary on the self-appointed morality police of our time.
