Bear in mind that
mensch translates better as "
person" than as "
man" anyway. This can only be
intentional - if
Nietsche had wanted to write
Mann und Ubermann there wouldn't have been anything to stop him from doing so.
For all his faults, and he had many, Nietsche was no-one's theoretical misogynist or even Nazi. He believed in transcending religion, rather than slaughtering people.
