Actually guys the ubermensch ws supposed to be a man who had his own point of view and set his own morals. Much like a sociopath. However if you read further nietzsche says that over man derives his set of morals from himself and most importantly does not impose himself upon others. This last bolded trait sounds more aspie to me and it against sociopaths who need to impose themselves upon over for narcissistic supply. Also the ubermensch was on who is supposed to have "perfect virtues", this to me is the most significant clue that Nietzsche was talking about aspies of the day.
Ubermensche means overman. This means that he rules over himself and was not meant to say that he rules over others, however this misinterpretation is pretty understandable. I leave you with this final quote: "is the one who is willing to risk all for the sake of
enhancement of humanity".
