The idea that all the people locked up in mental hospitals...

The idea that all the people locked up in mental hospitals are sane while all the people walking about are mad is merely a literary cliche, put about by people who should be locked up. I assure you there is not much in it. Taken as a whole, the sane are out there the sick are in here. For example you are in here because you have delusions that sane people are put in mental hospitals.
