Lifestyle choices & mental illness? Do too many inappropriate (to you) lifestyle choices cause mental illness?
Actually, I understand to some extent 8's meaning.
Let's look at transgenders as a pretty easy example. Someone born genetically female, who's convinced they are a male, and should actually have an appendage which they do not have (not to mention a whole host of secondary sexual traits)... If this weren't in any way related to sex, we would probably classify this as a mental illness (just look up "Body integrity identity disorder").
To some extent, anything that is not within the immediate range of "normal" becomes classified as a mental illness. Transgenders, homosexuality, bisexuality..... or to strike a little closer to home, obesity, addiction... anger....
Of course, even if you want to look at it as a mental illness, we generally try to accommodate members of our society who DO have mental disorders to ensure they can live as normal a life as possible (ie, making accommodations in schools for children with autism or ADHD...) so even if you chose to identify another person's sexuality as a mental disorder, that doesn't actually absolve you from anything.
