Anyone can grab an article or peer reviewed research that validates their bias.
So us throwing articles back and forth will be futile.
I am speaking of “mannerisms”, there are certain behaviors in males and females that are clearly visible without having been taught to children.
There are certain ways my daughter sits, crosses her legs, speaks, responds emotionally, etc that are definitively feminine and those things have never been taught to her.
The same goes for my nieces and nephews and other children I have been around.
It’s no different than having to teach children to not be selfish, rough, mean, etc.
Those behaviors, mannerisms, instincts are hard wired.
At the age of 3 my daughter knew on her own that she and the other girls were very different than the boys in her class bruh
