Here is a wonderful article from NPR about a whole Belgian community that has a very different take on dealing with the mentally ill person. Mental illness is not viewed as something to be afraid of or to treat. The mentally ill strangers in this town are placed into the homes of the citizenry, who then take the responsibility for watching over and helping that person.
There is a process to be allowed into this community if you are mentally ill. They do screen for violence and antisocial behaviors, so they have very few problems in the community. Mostly, these people live lives full of support and help but not control by others. The community simply views the behaviors of their visitors as just who they are and they accept them exactly as they present.
I am truly amazed at this community and wish we could do such a wonderful thing here in the United States. The treatment of mentally ill people in our country is not harmless and does not encourage living a fulfilled life. Please read the entire article and make up your own mind about this remarkable community.
