Narcissism comes to mind, but like you, don't have the expertise for a diagnosis. But when he starts insulting highly qualified professionals with decades of experience in their field and posts totally uninformed nonsensical crap instead, then it starts to become clear it's pathological. He may not be able to help it. Whatever the reason, it's becoming more disruptive to PW over time. It can be funny on occasion, but the insults to a whole community are becoming more numerous and think he's now at the point of needing professional help.
