I feel like what he's doing is some form of denial. Like how guys on 4chan will talk and fantasize ENDLESSLY about traps, yet insist they are not gay. They feel like it's an escape clause, but the rest of us aren't stupid. Nobody willingly envelopes themselves in that kind of discussion or content without being REALLY into it.
All of his defensive blathering is basically just a more complex, yet no less transparent, way of saying "Haha, just for fun"
