I see typology rather than as being a literal hard-in system, as being symbolical traits in which to assign oneself, and it is a way to explain how someone has a specific temperament or trait, rather than an objective hard truth of someone being entirety of their type.
You see a lot of followers of typological mean who treat their chosen typology (or typologies) as a gospel and hard Biblical rule.
I see it as a harmful notion, since things often are grey area, often muddied by psychopathology, belief, and life experiences.
I think if you have a combination of various traits, you can get along with a wide variety of type because somewhere along line in the system, the symbols, you can have traits that meet compatibility.. It is sort of like astrology in way.. You can find any reason to see compatibility/incompatibility... And there are so many symbols to denote trait, yet the mattering thing is which traits are most central and which ones you value most in others with your own combination of traits..
It just appears as if people want use typology as a template, perhaps because they have met desperation in relations, or they have exhausted in the try of other resources for their own betterment... And it is a matter of how you choose to connect the constellation, as constellation at end of day were people's interpretation of how dots should align, and all these systems are equivalent to the stars and how they can be used to connect.
