I think that fundamentally the argument was that there is no such thing as AS people but there are just men, or the socially inadequate or the shy, or 'selfish', that they do not have a 'condition' but are just 'themselves'. So normal behaviour (eg selfishness) is pathologised (explained by reference to an underlying medical condition).
I'm sure I have a vague memory of men talking in a sitcom (I think it was Friends) after Chandler had had a row with his Monica who had asked how she looked and Ross and Joey were explained how the 'rules' worked - never actually look, reflex answers eg 'does my bum look big in this?'/'no!'. I got the same impression with the radio programme - that it is 'normal' to have to explain social rules to friends who just don't get them.
Plus there was the guy whose psychologist mother had used him at a younger age in a teaching film she made about AS who said when he became an adult is was clear that he had been misdiagnosed and did not speak to his mother for 7 years.
What was not said was interesting. It was mentioned repeatedly that the diagnosis and notion of the brain being wired differently, was actually based upon behaviour rather than direct observation of the brain. However, the same could be said of any condition 'legitimately' listed in the manual. Even Tony Attwood didn't qualify his agreement that AS was not a mental disorder by saying that he believed that it was a neurological disorder and that AS is on the ASD spectrum.
imo it is not the case that greater understanding by others/desire to do things differently is needed but that NT methods of learning that rely on the implicit just do not work on people with ASD. It is not that learning is not possible, just that the technique has to be different in order to be effective. I got the impression that the AS were being reclassified as really NT, a bit odd but definitely not autistic, and that the 'oddness' is just more noticeable now because the roles the men play, and the requirements placed upon them, are different to and greater from that of their fathers etc. This led to women getting 'their man' diagnosed when he failed to meet their expectations.
Did we listen to the same programme?
