I would suggest a fallacious analogy. I wasn't writing about child sex offenders. Very possibly a completely different part of the brain that's faulty - and that's an issue, medical science and psychiatry know precious little about how the brain physically malfunctions in mental illness, or how to effectively treat the illness. Drugs mask the symptoms, but aren't really curative. Psychiatric knowledge (vis-a-vis brain functions in mental illness) is about as advanced as surgical procedures were in the 17th century. We are all prisoners of our individual brain chemistry and electrical behavior.
