Japanese throne sucession and why I never liked Dune, the book

In light of the latest princess to elope and marry in a hotel room, losing all rights to the throne, I remembered how back in the day the empress was known to be so depressed, she was virtually catatonic. The emperor of Japan has no male heirs, only a girl, whom I am sure is a nice girl, but she looks like she's never been allowed to speak in the presence of males and can't even sign her name correctly without a PR directing her. Namely, the Japanese royals treat their women so badly, they all suffer from clinical depression and have simply stopped reproducing. Their rule that only men can inherit is likely to bite them in the behind. As it well should. 

I thought of this and thought of why I never liked Herbert's Dune. 

The first thing to bother me, as I mentioned, was the names. Paul, Jessica, Dunkan, such nice midwestern wholesome proper names. Vladimir, Piter, as Russian names, are the disgusting imperial villains, and everything in concern with the Middle East is, well, exotic and primitive. The Middle Easterners - sorry, Fremen, are cave-dwelling, spitting, superstitious primitives, waiting for a white saviour, who love the desert and are loyal. I understand this was written in '65, when nobody really knew anything about them. But come on.

My problem, though, is the women. Worthless, sneaky, violent women. In the whole book, you only have two kinds: the scheming witches for whom nobody is good enough and have zero issue with slaying children, and mothers. The super saviour guy has a hot mother, that's her only role - until she has another saviour girl, and then she's done. The saviour super human male's chick is dead after she gives him the kids. His seed is so precious, the whole galaxy's politics revolve around it. The scheming mega witches need it so badly, no war, no genocide is too big to get it. And not like they give a flying duck about the quality of his character - don't forget Feyd-Rautha was the other candidate for the super mega saviour, in case Paul kicked it or was, you know, born a girl, whose only role would then be to get fucked by Feyd. Paul politically marries a chick he's never met, decided on treating her like shit for no other reason than the fact he decided it would be a good idea to marry her. If there are any other females in that story, you bet they are either scheming witches or wombs.
