against what exactly?
its not like he's going to hunting for his dinner
or he's headed out to raid another tribe
its 2015, for godsakes

what this typically means is teaching boys how to repress emotions
so as not to appear weak - the whole big boys dont cry thing
that also comes along with how we define 'masculine hetero alpha
actually, this is probably another issue to discuss-
because it does have repercussions

perhaps we should teach boys to be girls
we tend to be tougher anyway
(not physically maybe, but in ways that count in the longer run)
