The understanding of relatively highly-occurring afflictions such as PTS and schizophrenia is evolving to this day and it's a near-certainty that the DSM will be a different document 10 years from now.
I don't think we should be so cavalier about taking freedom away from people whose main transgression against the rest of society is making us feel uncomfortable when we look at them.
Just because it had errors before doesn't discredit the document in its current state; it's the product of scientific investigation. By it's very nature it will make mistakes and then update the conclusions as time goes by. Yes, of course it will be different in 10 years, but currently it is our best understanding of mental ailments and the knowledgebase has come a long way.
> main transgression against the rest of society is making us feel uncomfortable when we look at them.
The main transgression is that the victims are trapped in a cycle of suffering because their brains are malfunctioning and are preventing them from recovering or seeking help to recover.
Incidentally, are you aware that there is a difference between a mental disorder and a mental illness?
>And under what mental disorder should someone be institutionalised?
Under those that are responsible for causing a person to suffer and damage their own health and fail to try to recover, or seek help with recovery, as in the example above.
>All you've referred to is the DSM, so it's very unclear which illnesses and disorders you are referring to.
You've taken this comment thread on a totally different tangent. We're arguing a wholly different point now.
> Incidentally, are you aware that there is a difference between a mental disorder and a mental illness?
No, wasn't aware. I use them interchangeably.
There are a group of people in Australia called Ferals. They don't eat well, and they never bathe. They do it out of choice. I'm sure some of them are mentally ill. I wouldn't be locking them up in an institution!
