Early on, many boys give up. Once they turn it off, they rarely go back to it.

There is just one problem here - we're not in a jungle and boys aren't lions.

At 5 years old boys feel shamed if they don't push away from mom.

I think he's got it basically right, although I don't believe the system was set up purposely to hurt boys.

Many people, ... base their thinking about boys on the myth that 'testosterone = aggressiveness = boys,' but nothing in the research, mine included, proves that equation to be true … . So why do men behave so much more violently than women do, if there is no male 'violence chromosome'? When boys feel disconnected (from adequate love and support) and afraid of being shamed, when they harden themselves and then put on the macho mask, the one emotion they feel it's acceptable to show, and thus the only emotion they will show, is anger.

Waiting for the end, boys, waiting for the end.
