It's good that being told you're wrong doesn't nettle you. (In this you are unlike other INTJs.)
Your analysis is inane and misses the point. (In this you are quite like other INTJs.)
It is ironic that you attribute inane analysis and arrogance to INTJs while displaying both of them so clearly in your post. Have you considered that, according to your ludicrous and prejudicial version of typology (which seems entirely disconnected from the work of Jung or Myers) you yourself are likely an INTJ?
The "Byronic Hero" exhibits a constellation of pathological traits which can be exhibited by a person of any type.
Obviously. Perhaps you missed the post where I went over those traits and discussed their correlations with MBTI, then determined that INTJs fit best (but not exclusively). Perhaps you also missed the part where INTJ is the overwhelming consensus among other posters in the thread.
However, the chief redeeming qualities - charm and charisma - are not typically associated with INTJs.
Charm and Charisma are almost entirely unrelated to type, and many INTJs have been very charismatic. Consider John Maynard Keynes, Christopher Hitchens, Vladimir Lenin, and Martin Luther.
Quite the reverse. INTJ arrogance is generally repulsive to others.
Your distinction between "Byron the man" and "Byron the legend", is moot. Byron is the archetypal "mad, bad and dangerous to know" Byronic hero and the only non-fictional person attached to the type and is therefore, the only valid candidate for typing.
This is wrong in so many ways. Byron is certainly not the only non-fictional person attached to the type, as he himself considered Napoleon a shining example of the trope. And, as I said before, this thread is about a
fictional character type, so the only really valid candidates for typing are
fictional characters. Real people like Napoleon and Byron might bare some similarity to the trope, but they can't really fit it (except in idealized portrayals) because they're not literary figures, so literary tropes don't apply.
It is much more useful to consider this characterisation through the lens of psychological disorder than to impose an arbitrary (and ill-fitting) MBTI type upon it.
It is entirely possible that the traits of the Byronic Hero bear resemblance to psychological disorders like Narcissism or APD. I fail to see how that's any less arbitrary than pointing out a resemblance to an MBTI type though. If you think this is all a waste of time, then why on earth have you posted on the site 10,000 times? Are you just a really dedicated troll?
