Not only that, but the trend is cemented by the fact that only Lawful people are allowed to diagnose in the first place, so there is no checks or balances. In D&D, a few rolls could take care of that, but in the real world you'll get some hefty jail time... and a diagnosis.
Chaotic aligned people are being diagnosed as mentally ill by Lawful aligned people.
Unfortunately, it's frequently Lawful-{Neutral|Evil} judging Chaotic-Good, which is a travesty.
