Men are emotional as shit, hence the funneling of all of their emotions into recent movements like the alt right, tea party, gamergate etc. Instead of properly examining how and why they feel a certain way and expressing those emotions in more healthy ways, they lash out. In many ways society seems to say the only emotion that men can express is anger, and no matter if they are experiencing anger or not it is often expressed that way.

I won't deny that sometimes women are socialized into hiding emotions and they do it by just pushing the emotions down, but so often they are also told their emotions don't exist. As a test, look at any comment section when a women writes an article expressing her feelings about being sexually assaulted/harassed and see how many people, particularly men, try to insinuate the woman was feeling contrary to what her own words say! Some women internalize those views, and start to really believe that their very valid feelings aren't valid and never existed.
