there are peer reviewed studies such as this one that espouses the view that rape might be genetic:
A Natural History of Rape: Biological Bases of Sexual Coercion (Cambridge, MIT)

however there are also studies and responses debunking the sociobiological impetus of rape.
some of the resistance has come from the implications of accepting the conclusion etc not necessarily an outright refutation of it.
just saying it's not so black and white.

i happen to think it can be nature, nurture or both,
a comprehensive prevention policy would address all.

that's all i got.
