There are hundreds of species in the world which engage in non-consensual sexual actions, including many primates. This isn't really debatable, so it is 'natural' in some interpretations of that word, however how it applies to human interaction is more complicated, because we are complicated. Like you said, a pathology and usually related to fear.
However, I said a woman was 'attacked' not raped. I picked my words carefully. You said raped. The reason I said 'attacked' was because I wasn't saying the man in this story experienced the equivalent harm of rape - I'm suggesting he was attacked by the malevolence of another human being.
Matriarchal societies have zero instances of rape sounds like an Elle Beau talking point - but I'd suggest it's more complicated than this and the various ethnographic studies require some overarching analysis and clarity. Also, there's a blind spot here and one that's interesting in law. Here in the UK there are no female rapists, because our definition of rape requires a penis - though we could argue Isla Bryson is an exception. (though I wouldn't do that.) https://medium.com/p/2af13254adcb
I can tell you from working in secure mental health that there are plenty of 'interesting' relationships between mothers and their boys. That research is still to be done and there's still some complicated questions at play. Before I'll whole-heartedly endorse the Elle Beau position of Matrilineal utopia I want some more discussion.
And no, you inferred a false equivalence because you brought rape into the discussion where it previously wasn't - and then you decided to be outraged at an argument I didn't make. Does that make me a troll... I don't think so, but as always it depends on the interpretation you give it.
