Yes, it was a Joke. But it points up a real question.

[4th law of robotics]

12. I think most behaviors can be linked to a combination of society/genetics

So for instance we're wired to seek out the best possible mate we can find. That's been beaten in to our brains by millions of years of intense selection. What is considered "best" in a mate and how you go about acquiring one is however influenced by society. The basic behavior is biology, the external details are society.

The problem many feminists make is to assume it is 100% social conditioning.

They latch on to the details that are influenced by society (why are skinny women valued now but heftier women were seen as beautiful in the past, huh!??! Clearly it's entirely social conditioning) and use that to argue that the biological basis for those behaviors must then be social conditioning as well (men aren't really interested in sleeping with pretty women. PIV sex is traumatic to women and no woman outside of the patriarchy would ever engage in it).

Needless to say that nature/nurture debate won't end any time soon. And given that we can't raise people in controlled environments from birth for the sake of a study we likely won't hammer out all the details any time soon. But it's worth keeping in mind that society wasn't forced on us by some third party. We created it from scratch based largely on innate traits of H. sapiens.
