We seem to be miscommunicating, or possibly using different terms or something.
An individual child is not raised "in general", it is raised by one or more parents, yes. However, 'children' as a whole are raised mainly by parents on the middle part of the bell curve. Ignoring the norm in favor of the exception does not make the norm go away.
In general, women and men are not the same, and mothers and fathers are not the same, and do not parent exactly the same, nor role-model exactly the same. I'd think this was obvious... uncommon exceptions aside.
