I need to "out" someone who most likely has NPD. (I've been browsing this forum as well as doing general reading, and every odd or hurtful thing he's done lately has its analog here.) This would be a limited communication to the board, paying members and volunteers of a local nonprofit corporation.
I understand that this can be risky in terms of retaliation, but there's already been some back-and-forth sparring, so I think I have the measure of this man. I don't think violence, smearing, financial or career sabotage are likely. (We have both threatened to go legal, but his threat was purely ego-driven and would have been a disaster for him had he gone ahead.) So please don't warn me off -- this needs to happen, to help prevent others from being similarly abused.
I am asking for a good way to describe this man's abusive behavior while avoiding the use of specific or general diagnostic terminology; I'm hoping to further protect myself against a lawsuit for defamation. I am not looking for legal advice; I've spent a lot of time in the law library and online, so I have a good idea of what, where and how I can discuss this without it being actionable in court.
But I'm a bit stuck on how to describe his NPD. I want to avoid the direct use of that term, obviously. I can't use "malignant narcissist" -- he's not that bad, and that looks like a term that's used for diagnosis. I thought of using "pathological narcissist," but that may also be used in diagnosis.
Currently I favor the term "abusive narcissist," which is certainly truthful based on his conduct, but doesn't seem to be something a doctor would pronounce as a formal diagnosis.
So my question is, would "abusive narcissist" be a good way to describe someone who IS an abusive narcissist, while still being a layman's opinion and not anything close to a doctor's diagnosis?
