In many parts of American society it is considered inappropriate for men to express any emotion save one--anger. When a man learns to express other feelings and not be so concerned whether as to whether others think he is strong or “manly” he takes a major step forward.
Sure, there’s a time and place to "come on strong and take no prisoners." But it's a denial of your humanity to oversimplify, hiding behind a narrow definition of manhood. Men must be both tough and tender. Maturity comes when when we understand which one is appropriate at what time.
