I completely agree with you wrt. to where most children are getting their actual raising from. This is amplified by the lack of direction commonly given by parents.
As far as defining masculinity, I mean it in the sense that psychologists use it: the traits that are generally common to males.
Children learn from other children. Usually older children. Children are largely being raised by the state and that is never a good thing as it leads to conformity. Educational institutions look at children as future workforce and not as individuals.
