Amos Oz defined a fanatic as unable to comprehend what they themselves say, because they don't really mean it (but still say it!) That's the thing with calling people "pathological", it becomes so "big" that it seems "outside" personal emotions. Contrast "big labels" to "big lies". People aren't really even aware of what they say (why it is so effective for ritual human sacrifice. ) "Small labels" on the other hand, like "idiot", people can relate emotionally to them, so they seem "worse", while "hysteric", "drapetomanic", "bipolar", "schizophrenic", "autistic", seem "milder" (they're not of course, but says a lot about human psyche when we give up control! )
I'm very much against "big labels" because of their power, since I've seen what they do to people.
