Sorry. If a person (whether a person of faith or otherwise) calls same-sex relations "the dark harbinger of chaos and sexual anarchy that could doom even the strongest republic," that person is a homophobe. Kelly Johnson's practice supports a form of Christian conversion therapy. Re: Stephen Colbert... he is unabashed about his political views. But, he's no hack. The man is brilliant... and a devoted Catholic.
I don't question anyone's beliefs unless they use those beliefs and cherry pick from scripture to make themselves morally superior and justify their biases. The Johnsons are such people and folks need to know about who they really are.
