In all of his works there's always a sense (at least for me) that Nietszche says: "do that, don't do that, don't be like that, be like that".
Did he really wanted us to become better? If that's not the case, why he says, for example, that women's solution to all their problems is to be pregnant? Why he says that to women? And why it seems that he is saying that to us, men, as a way of dealing with them (women)?
And what is übermensch if not something that in a simplistic reading would seem to be something to achieve? (actually, he says that)
What's the purpose of Nietzsche?
