I've been seeing this trend for awhile now, and it's just been growing to an insane level. I hit my head on the table repeatedly when I heard about the latest that people with anger issues now suffer from a medical condition.
The risk is this: The more things we label disease, the less we label as transgression. If you think of your problem as a "disease," to be treated like a disease, that lets you off the obligation to change that behavior.
Sums my feelings up pretty well.
