The impression I have of current thinking on the interaction between "nature" and "nurture" is that this is one heck of a complicated mess on any issue at all to which it has any relevance. Back when we were arguing one against the other we could indulge in simplicities. But now that we know for a fact that we have both and that they interact in all kinds of complex ways it's much, much harder to envision the real possibilities.

Non-scientific thought, the kind that all of us indulge in every day, is just not up to dealing with that degree of complexity. And this issue directly impacts discussions of the kind we're having here: talking about the "spectrum" of gender behaviors (as well as many other issues). I don't know that it's ever going to make sense (in terms of always limited resources) to try to tease apart in specific cases the almost infinite strands of nature on the one hand and nurture on the other. And since each individual is and will be different, that means (to me) that we'll never have any good and reliable generalizations either, at least below the highest level of generalization (i.e., at birth, from genitalia: "This is a boy;" "This is a girl").

So where does that land us? It lands us, (I think) with accepting each individual as an individual, not using the gross stereotypes utilized in the past, and taking as given that individuals will always be different one from another in many ways. Take care!
