Motivational speaker Frank Turek has suggested that a gay gene would not make gay marriage OK, media watchdog RightWingWatch.org reported.

Turek's 143-page anti-gay marriage book Correct, Not Politically Correct: How Same-Sex Marriage Hurts Everyone has led him to lose speaking gigs at Bank of America and Cisco Systems.

During an appearance on In The Market, Turek told host Janet Parshall that a gay gene wouldn't make gay unions OK.

“Frank, let's clear the air about this idea of the discovery of the gay gene, there has been no substantiation that there has been the discovery of a gay gene, correct?” Parshall asked.

“No, but even if there was it would be irrelevant. We're all born with an orientation toward bad behavior, but because I'm born with an orientation toward bad behavior that doesn't mean I ought to engage in that behavior. If I'm born with a predisposition to anger and I start bashing gays and a gay person says to me, or a person who wants to engage in homosexual acts says to me, 'Well you ought not do that' and I say 'Don't blame me. I just have the anti-gay gene.' What would they say? They would say 'no you must resist that,'” Turek answered.

“We all have things we ought not act on, we all have desires that we ought not act on. The worst thing we can do is say, 'Look I was born with this desire or I learned it as a child and even though I know it leads to destructive behavior I ought to do it and you have to not only accept that, you have to endorse it by taking my behavior and enshrining it by government endorsement by calling it marriage.'” (The audio is embedded in the right panel of this page.)

In an op-ed published at the AFA's Rightly Concerned blog, the Charlotte, North Carolina-based speaker wrote that he's out to warn gay and lesbian people to avoid getting run over by a truck.
