The benefits of intact biological families were emphasized on a "Building a Marriage Culture" panel at the National Review Institute's 2013 Summit, "The Future of Conservatism." One of the panelists, Doug Mainwaring, spoke of his personal experience as a gay man who came to realize that his own children need both a mother and a father.

"For a long time I thought, if I could just find the right partner, we could raise my kids together, but it became increasingly apparent to me, even if I found somebody else exactly like me, who loved my kids as much as I do, there would still be a gaping hole in their lives because they need a mom," Mainwaring, co-founder of National Capital Tea Party Patriots, said.

Mainwaring is now living with his ex-wife so they can co-parent their two teenaged sons.

"I don't want to see children being engineered for same-sex couples where there is either a mom missing or a dad missing," Mainwaring explained. "Somebody needs to stand up for the rights and needs of children in an age when the selfishness of adults seems to be trumping those rights."

Mainwaring receives many surprised reactions when he explains that he is both gay and a conservative. Someone asked him once, "You're gay, how can you be a conservative?"

The audience laughed and clapped as he recalled his reply: "You're an adult, you have children, how can you be a liberal?"
