Perhaps the most important argument against same-sex marriage is that once society honors same-sex sex as it does man-woman sex, there will inevitably be a major increase in same-sex sex. People do sexually (as in other areas) what society allows and especially what it honors.
One excellent example illustrating this is an article recently written in the McGill University newspaper by McGill student Anna Montrose. In it, she wrote:
It’s hard to go through four years of a Humanities B.A. reading Foucault and Butler and watching ‘The L Word’ and keep your rigid heterosexuality intact. I don’t know when it happened exactly, but it seems I no longer have the easy certainty of pinning my sexual desire to one gender and never the other.
(Michel Foucault is a major French "postmodern" philosopher; Judith Butler is a prominent "gender theorist" at UC Berkeley; and "The L-Word" is a popular TV drama about glamorous lesbians.)
I interviewed Anna Montrose, a bright and articulate 22-year-old woman, on my syndicated radio show. She is a fine example of the type of thinking and behavior a homosexuality-celebrating culture — such as that at our universities — produces.
