That was him during an interview, not writing. Furthermore it's important to distinguish his satire from his viewpoints.
Of course the comment is a tad tongue-in-cheek. It is speaking more that he is against much of the LGBT movement in which he should be a part of. Falling under the "G" and by not conforming to the widely held beliefs he is homophobic. I fall under the "T" but I'm disgusted with half of what the LGBT movement pushes for and have on many occasions been called a transphobe. Especially in regards to my usage of "tranny", as I stated.
A bit tongue-in-cheek myself: If I weren't a transexual I'd be one of the largest transphobes I know. Largely because I refuse to let people police my speech.
