The entire point of today's "social conservatism" with respect to gay people is not to encourage responsibility, fidelity, marriage or love among gay people; it is to tell gay people to marry straight people and suppress or "cure" their sexual orientation. In fact, do yourself a favor and see if you know any social conservatives who actually favor social conservatism for the three percent or so of humanity that is gay. It's a useful test, no?
And, of course, we know the actual consequence of such policies: they undermine and destroy family life. Here's one story of a woman who realized she had married a gay man eleven years previously:
There are so many obvious questions for a wife like me: Didn't I realize he was gay? Did I ignore red flags? And if I had suspicions, why didn't I confront him earlier or divorce him?
I suppose I was always suspicious, but I was in denial. Early in our relationship, Chris told me he'd had homosexual experiences as a teenager but assured me it was youthful curiosity. I didn't think there was anything wrong with being gay I have an openly gay cousin. And I didn't care what went on behind others' closed doors. But I also didn't believe that a gay man would ever be attracted to a straight woman, and I was naive too naive to see why a homosexual man would marry and spend years lying to his wife, his friends, his family and himself.
