Christopher Chope, one of the Tories who voted against gay marriage, wanted him, in the interests of equality, to offer civil partnerships to straight couples too.
Cameron wasn't going to fall for that. "I am," he declared, "a marriage man. I am a great supporter of marriage. I want to protect marriage, to defend marriage, to encourage marriage." Civil partnerships would only weaken marriage. I had a vision of Cameron as Marriage Man, a superhero who leaps into action whenever marriage – straight, gay or transgender – is under threat. He wears grey, striped, figure-hugging underpants, a black cape with tails, and a silk topper. Young folk would call him on his Marriage Mobe.
"Marriage Man, I want to marry my boyfriend, but my parents say he's a no-good waste of space. I need your help!" Faster than a Rolls trimmed with white ribbons, Marriage Man races to the spot, biffing the anti-marriage parents, kapow!
Sorry, got carried away there.
