You've described learned behaviors among family group/s. A male child learning to chose submissive, "more feminine" behaviors almost certainly because he found some communicative and affectionate reward in doing so.
So, "feminine behaviors" are a result of positive reinforcement, as in learned behaviors? Men and women aren't different to start with and are merely socialized differently? Might be that you've reduced your argument to the point that it has become meaningless. It's just not that simple.
You have reduced very extensive issues and conditions to mere assumptions on a social basis.
I agree that these things are not "that simple" and no, I have never suggested here that "feminine behaviors' are a result of positive reinforcement" and all the rest that you suggest I suggested.
Which I didn't. Perhaps you're confusing what I've written here with the simple suggestions someone else was making as to some male children she'd see in another family growing enlarged breasts and assuming differnet "scents" and such.
Absurd generalizations. Also indicative of the sexualization of children, assigning sexual predispositions to children based upon childhood morphology, without medical examination to rule out physiological conditions.
But, to repeat, no, I've never suggested here, anywhere, nor never would, that "'feminine behaviors' are a result of positive reinforcement, etc."
