A few years back I was skimming through a book in a second-hand bookshop.

It was written by a feminist, and in the back was a glossary of feminist terms.

One of the terms was described as the belief that all men want to stab
women, and therefoer hurt them, which is their motivation for having
sex.

What is the name of this belief?

Neuroticism

She had it all wrong  - backwards:  men want to have sex with women
(very normal and biologically programmed); any desire to stab them is
transference of this impulse when it is frustrated.  Of course, this
is not always the case.

I suggest "Brunhild Complex" for the feminist's misgotten attitude.
Brunhild said she would only marry a man who could prove that he was
stronger than she.  Günther  - with Siegfried's help -  wins the
contests, but in the wedding night, Brunhild easily manages to
overpower Günther and ties him up and hangs on on the wall.  The next
night, Günther secretly lets Siegfried take his place, who easily wins
over Brunhild, but in some versions of the story lays his sword
between them and does not deflower her.

"Heaven has no rage like love to hatred turned/ Nor hell a fury like a
woman scorned." by William Congreve in The Mourning Bride of 1697.
