Thanks to Tennessee Guerrilla Women for this. This is a potential question posed to candidates on the YouTube debate.
It was so good, I transcribed it:
Good evening, gentlemen. My name is John. I am twenty-three years old. I am a Christian. And I have also been an open homosexual since I was thirteen years old. But I am also an American and I strongly believe in the separation of church and state. And I offer you this challenge, all of you. Logically explain the reasons that you believe that gay marriage should be banned without referring to your religion or the Bible. Thank you.
