.......PS: I worked for a good few years helping to provide services to people with learning difficulties/disabilities (previously known as mentally handicapped) and I just happen to think the word 'moron' is denigrating in the extreme.
My wife works for a "special school", so I understand and agree fully with what you mean, and not at all in a "politically correct" way, just in a human way. These unfortunate people are just that - people, not morons.
If people want to see what morons look like, then all they need to do is watch Crimewatch, or any other of the many programmes about low-life.
All the best,
