Look, describing a PSYCHOLOGICAL ISSUE (such as "cutting" or "homosexual behavior" or "narcissistic personality disorder" or the like)... which are certainly REAL issues... with a PHYSIOLOGICAL ISSUE (which is what real addition, including alcoholism, is)... that's just NONSENSE.
If there weren't huge taxpayer-funded grants going to people to "study" these newly-discovered "additions," we'd recognize them for what they are... SYMPTOMS of known psychological issues.
I have yet to meet a homosexual who can't point to some disfunctional situation or event in their past. The boy who lived without a father and whose mother and grandmother expressed their spite and hatred of men... the girl who was sexually abused by her stepfather, etc.
