Your reply is nearly as long as the piece I wrote. Is it reasonable to expect someone to "make a life decision" based on it? A 400-word piece can't address all the aspects of narcissism - only a sliver. That's why it's part of series, and all the pieces are being archived in one place. I also can't repeat the basics of narcissism in every piece, when they're meant to be short and easily digestible. I understand the concern that people need more and deeper information. I also understand that I can't provide all of it. I'm not a clinical psychologist, and I don't hold myself out as an expert on Narcissistic Personality Disorder, which is a psychiatric diagnosis that I'm not qualified to make or opine on. Are you? Narcissism is, however, a descriptor for a pattern of behavior, and I try to discuss it in ways that helped clarify it for me when I needed it. I'm paying forward what I learned. I use layman's language and keep most of the pieces short, because the feedback I've received from readers (most of whom read more than one piece) tell me that's helpful.

I trust that my readers are smart enough to see the strengths and limitations of my contribution and find other sources to fill the gaps. They know a 3-minute Medium read can't fully address much less solve a very serious, sometimes dangerous problem. You obviously know that too, so I don't understand why you think the rest of us couldn't put that together and thought you had to write out a condescending primer in my replies.
