'many people who have a personality disorder (as opposed to the inflammatory "psychopathic thugs" he refers to)'
.,,.
A clumsy & tendentious (*) distinction, Ian. Psychopathic thuggery is a 'personality disorder'; that doesn't mean that we have to be nothing but 'ah poor diddums' to those who suffer from it --

assuming they genuinely do, and are not merely exploiting the well-known possibility that they might: do you purport to be able infallibly to distinguish?

-- The experiences of those who cross the path of the individual in question are equally disagreeable, whichever summarising phrase for his condition may be invoked.

*(why "inflammatory"? There's an inflammatory boo-word as ever was! Purely a statement of the facts of the matter, I should say!)
