When masculinity harms men.

Studies show 95% of the most violent crimes are committed by men.

What's the cause?

Well, the one below, might not be the only reason, but definitely important enough to be addressed. Since childhood, the Great Indian Parents, elders, neighbours - all start yelling at a boy when he starts crying - 'ladke rote nai'.
Even if they are happy tears, still - the saying remains the same -'ladke nai rote'.Par kyun? 
Is question tak koi nai jaata.

Crying is also a form of 'expression'. When one stops expressing, in the false pretext of being too strong - all those emotions don't bury themselves, they evenually come out in some form or the other. Generally, in the form of anger, and would most probably be vented on another being considered less potent than oneself.
Every human needs to 'Emote'.
That's a basic necessity!

By abstaining one from doing so, we are making them apathetic towards fellow human beings. We are in need of a world where apathy is replaced by empathy, not one, where apathy is considered masculinity.

And by empathy, what I'm referring to is an instinctive mirroring of other's experience. As moral beings, we have the imaginative capability to place ourselves in another's situation, and form an idea of their sensations. By experiencing the pain of others, the intensity of one's reaction can be lessened, making the reaction less violent.

As Emily Bazelon puts it, "The key is to remember that almost everyone has the capacity for empathy and decency - and to tend that seed as best as we possibly can" is what makes the difference.

'Change' is 'possible'.
