No, you quite clearly have no understanding of the manifestation of type functions and are basing your assertions solely off of your own perception, mismatching type characteristics to suit the impression you received. Your entire argument is incomprehensible. You have some nerve to state that he lacks knowledge of Hitler, especially in the face of such irony.
Hitler was introverted, which we know from his own descriptions of himself and those who knew him. During his stay in Vienna as a young man, he spent much time alone reading books and visiting opera houses, and arguing his political stances with Marxist workers. Hitler was described as a polite and reserved individual by those who knew him most intimately. He was a theoretician and was bored in school, preferring to plot his own course of action; wishing to become an artist. He was highly critical, enjoyed reading scientific and technical works, and was not averse to engaging in heated arguments. He was clearly an organizational planner, a TeJ, and the second volume of Mein Kampf was entirely devoted to the structure and organization of the NSDAP. To claim that Hitler was a P is the height of ignorance and absurdity. There is absolutely no indication that he was a P, considering that he led a very structured (mentally, if not always physically due to his poverty) and goal oriented life, especially in the fact that he implanted his own goal oriented idealism into his movement. Ps are simply not the type of individuals who concern themselves with planning and organizing movements based on hard struggle, which make value judgments and may be considered "narrow minded" by the "liberated" Ps. I find proof of this claim in both the theoretical construct of the perceiving type, and in the fact that modern day Ps, especially NPs, are individualistic by nature, and embrace either humanitarian or libertarian philosophies, and not philosophies that would require them to sacrifice their lives for a greater movement, much less one which demands the obedience and discipline of National Socialism. Ps could never lead, or hope to conceive, of such a disciplined political philosophy that rejects individualistic nonsense, and in the case of NFs, political correctness and the humanist delusion. Not to mention the fact that I don't know any NP who concerns himself with political endeavour, least of all NFPs. INFJs and ENFJs are also out of the question for the same reason that all the feelers are: they are much too easily swayed by the utopian idealism of Marxism rather than the idealism of Hegel or Kant, or the humanism of Kierkegaard over the existentialism of Nietzsche, and prefer social harmony over realistic social structure which involves hierarchy. Besides, Fs are much too cowardly and averse to conflict and social stigma to involve themselves, much less lead, in a movement as aggressive as National Socialism; again, we see this truth in modern day Fs, especially of the NF variety. Have you heard of the Führerprinzip? Does this notion strike you as P? It was developed by Hitler.
I don't understand the association with extroversion simply because he was capable of moving crowds. Are you serious? Can introverts not be motivational speakers? Introversion has no bearing on one's ability to lead movements or speak to crowds. According to your logic, introverts could never be in positions of power, despite the fact that they are more than likely overrepresented in political/military leadership roles. Speaking to a crowd and moving it simply means that you understand crowd dynamics and are capable of transferring your passion unto the crowd. Extroverts are no better at this than introverts. Extroverts may make for better clowns, but not for better motivational speakers. Also, will you honestly make the argument that Hitler was extroverted due to the fact that he attended parties and celebrations throughout his political career? Honestly? Is this not ridiculous? He was a statesman! What do you expect!?
Organizing movements as exclusive as the NSDAP is highly NTJ. Hitler did not concern himself with pandering to those he considered "parliamentary simpletons."
Regardless, there is little point in continuing, because as sgtmac stated, Hitler was without a doubt an INTJ. The INTJ personality fits what is known of Hitler through his close associates, his manifesto, his many speeches, his letters, and apparently his OSS profile, best.
