From what I've read about the Fuehrer's upbringing, he very much had an NF persona; his father, probably an SJ, abused him because he was a dreamer.
And in Mein Kampf, his intentions were clearly mapped in his mind. By this time, he had a clear vision of a Third Reich. He was very future oriented, SPs are very present oriented.
And any dominant Extravert has power to manipulate a crowd (Martin Luther King, Jr., ENFJ, technically did this, as well), but what's different is the person's intentions, which is an entirely different conversation. One would argue that MLK was more persuasive, but that's really just a more positive way of saying manipulative.
His interests were art, philosophy, symbolism, and history -- something that many NFs seem to be interested in. Hitler was also a generalizer -- an iNtuitive trait -- and combined with a J function, allowed his stereotypical views to be unbending.
SPs and NJs could seem a lot alike. An SP, however, is physical for the pure enjoyment, while an NJ might be physical to achieve an end.
And lastly, an F preference. Hitler's vision was for the good of the people he considered superior (this is something that personality does not dictate). In unbiased terms, he had a dream for the greater good of his own personal view of humanity.
But that's just my impression...
