Yeah, but those men tend to live like insects. When you live like an insect, emotions don't matter...or they eventually blow their brains out. Look at the suicide rate in Japan, and rural America where this attitude dominates.
Some of the most successful people are gaping vaginas by those standards. They cry, but they don't give up, and crying tends to aid in recovery, and not giving up is all that matters. You release stress, and get over things quicker. Keeping things in can be a considered a weakness as well. I say this as a person who resists crying; especially in public.
Sure, we don't need a society of blubbering fools interrupting every public gathering, but in this situation, DC can blubber all he wants.
At least it wasn't me.
