"Anger, that is really what we think
about when we think about emotional
men," she continued. "They are
subject to social sanctions if they
deviate from masculinity. If you are
perceived as failing at it, you are
subject to being called a fag, a pussy,
a wimp, pretty much what women
are, right?"
"So when you have this limited ability
to sort of express your emotions and
possible feelings of emasculation, of
low self esteem, how do you really
[deal with] that? A lot of times they …
engage in violence. They need to
compensate for their loss of
masculinity in the most manly way
they have access to, and
unfortunately, a lot of times that's
violence."..."
