The thing which I think gets missed out of these discussions is the notion of community. We're such horrific individualists in the West that we seem to see nature and nurture as distinct, which of course they aren't. The nurture of a child is a product of the combined abilities (from nature and nurture) of the people in their family and community. There is no "I"; our DNA and mores are all part of a greater whole.
That's because we haven't yet cornered good ol' "free will" yet like we have this subject, or if we have, it certainly isn't trotted out as regularly and forcefully by the Right, likely because the virtue of the concept is to support punitive discursive apparatuses.
