Havn't time to go through all the points raised. I agree with some of them.
Eno there is a difference between learning difficulties and mental illness.
You see people confuse this. Some are born with learning disabilities. THIS is
different to mental illnerss. People can be involved in a car accident and damage their brain causing weird behaviour as a result. THIS is
different to mental illness. The first is genetic and a defect. The second is physical and treatable with drugs. Both of these are very different to mental illness. Mental illness cannot be curred by drugs. It can be influenced, but not changed. The mind is not an organ. Mental people have a brain that looks the same as an ordinary person. There is nothing physically wrong with it.
Mental disease therefore, as it is not visible nor literal to touch, is unique, even doubtful and explicitly complicated. Perhaps another discription of it can be a "corruption of an invisble sense" which could be deliberate or a case of just not bothered or concerned. Simply void of any sense of wrongdoing and unable to tell the difference between good and evil.
Oh and Doug - I actually among a population of mental folk! From my bedroom window is the biggest mental institution in the whole of Northern Scotland.
Our of another window is a lodge for those with learning difficulties that have a freedom under supervision life. Then on another side of the house is a place for those with weird behaviour who look after themselves (I guess with extra help ready if needed but they live in their own homes). Now these latter two are very different from mental illness as I have already said. However, people confuse them.
Finally, I know people with mental problems myself. One person I know has a severe depression that got so bad he voluntarily went to the "New Craigs" (the Mental hospital) for treatment. It seemed to work and for a year he was free, before it returned. Not sure on the intricacies though. Another person I know is a really old lady. She was decided fit for being forcefully detained there for a couple of years. I knew all along she wasn't mental. She was just stubborn and had a didn't care attitude to life. She was pleasent and wouldn't hurt a fly but very strange!

I knew her well enough to see through it all and although she was a crank by no stretch of the imagination I insist if there is such a thing as mental illness she never had it. She now lives in an old folks home. But that is a long story and I won't go down that one.
Anyway, thats enough chatter for now!
