Thanks again, everyone, for your thoughts on this topic.
Prospero, all excellent points, and I agree with you. Thanks for sharing those insights.
Jem, I didn't see this documentary, but your insights are exactly what I'm talking about. It sounds like whoever the director was was an expert at 'showing', not telling.
As regards your 'by the way' comment, no offence taken, it's a good question. The difference between 'Disabled' or 'Handicapped' may be splitting hairs. However, black people, for similar reasons, don't like to be referred to as 'coloured'. Indeed, I may feel that that is splitting hairs. It's just what has become accepted language, and anything else is archaic. Having said that, 'handicapped' is still used in the USA, so (as they'd say over there), 'go figure'. If I was to split hairs, I'd say (and this is only my personal feeling), 'handicapped' implies an inherent disadvantage: if you have a handicap in a sport, you're inherently 'not as good' as someone with a lesser handicap. And people who have a handicap in golf, for example, quietly just accept this as 'the way things are'. (Yes, I know you can work your way up in sport; 'lessen the handicap' etc, but that's not the point, really.)
'Disabled', however, implies that we are not inherently 'disadvantaged'; we are only made so - we are only 'disabled' - by society: prejudice, lack of awareness, stereotype etc. Notice the difference between being made 'disabled', and being inherently less 'able' (or 'unable'
. All this relates to philosophy really, specifically the social theory of disability, which basically says the above: society is the 'disabler'.
Sorry for waffling; I just thought you'd asked a good question. You may disagree with my answer, but that, I believe, is why many people make the distinction nowadays.

<Added>Regarding the society comment, look at Prospero's experience above. Now, it's only a drop in the pond - I know - but if all of these conference buildings improved their access, 'disabled' would become less of an issue. Indeed, perhaps eventually, redundant. Just my opinion.
<Added>By the way, apologies, I should have mentioned I come from a position of physical disability. I'm not sure about terms used for people with mental impairments, you'd have to ask someone else about terminology there.
