The way I read it, his calling it a disorder is geared mainly towards the medical community: if it is a disorder, it's much harder to refuse treatment. Also, for a geneticist what he is talking about is a disorder, however one should consider it from, say, a social point of view. The thing is, for us words like 'pathology' or 'disorder' are quite strongly loaded, and from the interview it may be hard to see that he's using them in a somewhat different manner than how some of us are hearing them.
Of course the interview wasn't perfect. Still, saying "phhhhfffftttt!" is a bit much.
