Two Questions (well, really three)
When does a difference in opinion, understanding or perception cross the threshold and become a mental disorder? When does confidence and certainty become delusion? I am reminded of the story of a woman many years ago on CBC radio, who told how her parents had her diagnosed as insane and committed as an adolescent because she was lesbian. While I may not agree with her and I believe her behaviour to be wrong (yeah, yeah, I am on the conservative end of the spectrum here), I certainly do not think she was insane. So what is the difference between being "wrong" and having a fundamentally disordered perception, understanding and experience of the world? To adapt a saying: I may not know what insanity is, but I know it when I see it . Principally inspired (bits copied verbatim from my comment) by a post on Barbara's blog .
