I had a different take from ozombie's friend. He says
That is to say, for most people, the world doesn't revolve around sex.
I didn't go chasing links, but what I thought of was all the gay people, especially at the DUmp, who are militantly gay. All they think is how GAY GAY GAY they are, and every thought is run through that prism.
You could say "the sky is blue," and they would say, "Yes, but what does that have to do with how fabulously gay I am???" That's why they hate the Log Cabin Republicans, and the GOProud. Those people think about economics, and other things, first.
