Nature vs nurture in this context means biological vs social causes.
Because you have one side saying every difference boils down to socialization. No biology allowed.
No there's nothing special about this topic in terms of this.
Everybody in every topic
wants to think of it in the terms you are. But you can't, because when you analyze the causal reality professionally, it just doesn't make sense to do that. It's intuitive to lay people, but in actuality useless. Because it is based on a false conception of how organisms work -- especially in America where this is most rampant, people are lured into this notion that we are our own little isolated temples and that our biology is a somehow meaningfully contained thing intimately tied to our individuality.
That's all bollocks. Your matter and cells and causal influence
and even your ideas and cognition (you export them by writing on post it notes and import by reading or looking things up on google instead of bothering to remember, etc. etc.) are leaking out of and into you every second in a super fuzzy impossible to distinguish way, and there is no truly meaningful distinction between your body and not-your-body, "biology" versus "socialization" or anything like that. There are colloquial distinctions of these sorts, but there aren't any that withstand scrutiny when you actually start zooming in and following causality around in an attempt to answer the initial questions.
The only place where there is an actual, hard, scientifically meaningful cutoff that remotely approaches what people want to talk about with nature vs. nuture, and which could actually be feasibly controlled for and tested, is genes vs. not genes.
Sometimes miscommunication is amusing. You do understand that men lack functional mammary glands, yes?
Yes.
My snarkily presented point was that "growing mammary glands" is a world away from "being unavoidably compelled to have sex, carry an infant around for 9 months, give birth, put them to your breast, and also have THEM suck milk out of it (do genes now mind control other organisms, too?)"
The breats are (partially!) genetic (partially reliant on not being malnourished, not being on hormone drugs, blah blah, so actually not even breasts are innate).
The
behavior is clearly not at all innate, by any crazy stretch of the imagination.
