Look, I know all that. Really, it's the statement that "there are no good cries for a boy" that's the problem, because it's just not true.
I pity that he's unable to weep from sadness anymore, but really, how does one cope with it, then? By lashing out in anger as he suggests? Drowning it in alchohol? medicating your way to happiness?
Come on, it's effed up, no denying it. The emotions are there, no matter how you react. Boys can cry, and should if upset enough. It doesn't have to be in public, but dammit, there can't be a permanent damper put on your emotions, that's just harmful.
