Hey Joe normally I love your stuff but I do feel as though you're actually taking away more than what Peterson is actually saying.
Psychopathic as an adjective to describe a state that's lacking in empathy, is not the same as psychopathy as a mental disorder. Peterson wasn't saying that you get antisocial personality disorder from having casual sex, he was talking about how divorcing sex from other aspects of your life as though it doesn't affect emotions, motivations, values etc, can lead to compartmentalisation and dissociation of those aspects of yourself, and that can lead to psychopathic traits and a psychopathic state of being.
It's like saying "that's narcissistic" or "so and so is narcissistic" isn't the same as saying "they have NPD".
Psychopathic traits are on a spectrum, just like narcissistic traits, we are all on the spectrum.
