I say this with the best of intentions. I highly, highly doubt you have cured it to the degree you believe, or that this is only the result of playing a foolish persona. If it is, you should stop with it fully, it seems neither foolish, charming or fun. It is only draining. And I have given a great benefit of doubt for this, until these last few comments where it’s beyond that grace.
If anything you should look into covert narcissism and see if you have not simply transmuted “overt” into “covert" in daily life, and that it slips through as the more grandiose version online.
I can not make an accurate assessment of this via an online forum, that would be unethical and false to assume, but I am saying - if you truly value working on this apparent flaw, and it has been a struggle, then this direction is worth exploring the implications off. And being aware that it could be a cognitive blind spot that not even a greater intellect would bring light to.
And for others: until he shows improvement, simply ignore responding anytime he elicits frustration or anger in you. It is for him to prove a change of behaviour. And if not from personal growth, at the very least his presence on these forums should be feed and starved as necessary. He will adapt either superficially, or (in better case) cognitively.
Also - It’s not all too kind of me to make such an open statement/scrutiny of another person as I have done, but with some protection via online anonymity I felt this would be best as it effects everyone else as well.
Now, after this quite disrespectful analysis, I say this: I deeply respect your skills and opinions @shamisen. You have showed enough analysis and ability in this thread to make it clear you have worthy opinions on this area. I have myself not given the same proof beyond “trust me bro” statements. But it all falls flat with how it’s presented and how you interact with others opinions. This is a genuine critical flaw, no matter why it shows up. And you have all the tools to be quite the charming character, rather than what has been seen here, which makes it even more frustrating to observe.
Edit: I will not answer this thread further. Feel no need to defend yourself. I place no harsh judgement anyways, only a harsh analysis. Don’t expect to sway my or anyone elses opinion by what you deem logical arguement for why or why not my analysis is true or false. Even your best attempt would be proof of nothing in public eyes. If anything the opposite of what would be desired. How you show up hence forth in other threads (and daily life, which can be said nothing about) is the only metric worth judging you on.
