Late last month, Molly Smith of Cleveland Right to Life and the National Personhood Alliancehosted Brian Clowes, the director of education and research at the Catholic group Human Life International, to discuss not their mutual opposition to abortion rights but the topic of LGBT rights, which Smith believes is inseparable from the anti-choice fight.

Over the course of 45 minutes, the two activists ran through an encyclopedia of anti-gay myths, including that gay men are prone to molest children, that people become gay because of abuse or neglect in their childhood, and that gay people have dramatically reduced lifespans.

Despite the fact that all of these claims have been thoroughly debunked, Clowes backed them up by saying, “The main principle to keep in mind is that every principle the Catholic Church teaches about sexual morality can be backed up by science, hard science and a lot of it.”

“Interestingly, you’ll find that if you get out of the homosexual lifestyle, you’ll be a lot happier,” he said. “If you’re living under God’s law, God wants us to be happy, so it’s going to be like that.”

The two went on to compare homosexuality to alcoholism, drug abuse and obesity.

“The term ‘gay’ certainly doesn’t apply here,” Clowes said. “It is a horrible lifestyle and it will kill you in the end. And those last few years of your life are not going to be happy because you’re going to be extremely sick, dying of cancer, HIV/AIDS, heart disease, whatever.”

Earlier in the interview, Clowes claimed that LGBT people are demanding tolerance and acceptance because they are “involved in all kinds of sinful, but extremely unhealthy activities and their conscience is bothering them.”

“If they feel bad about themselves, it’s the church’s fault, it’s the homophobes’ fault,” he said. “You know what I’m talking about here? So the only way they can get rid of that nagging little voice of guilt is to have everybody say, ‘It’s all right that you’re gay, we support you in your choice.’ And they will never be satisfied until everybody who opposes them is simply shut up.”
