Very good point. I studied a lot of Philosophy in college, and the postmodernist movement drove me nuts, but Foucault had a very good point in his paper on mental illness, that mental illness is socially constructed. The way I'd formulate the definition of a disease is that it's an atypicality that has a significant negative impact. What's a negative impact though? That's a value judgment, and most everyone has a value system that agrees in cases like cancer, but not on homosexuality. It's even situationally dependent. There is evidence that soldiers that measure higher on measures of psychopathy are more effective in conventional combat because they do not hesitate to kill.
