Liberal, as in, believing in liberty. Freedom. How many mens spaces do you know of, where a man is completely free to open up, with full liberty and freedom from immediate consequences, about feelings they may have inside of them?
There's actually not a lot. It's a reflection of masculine indoctrination, where men in many places are made to feel like they almost need to be ready to become a soldier at any moment. Guarded, careful. It's no good, unless your country is actually at war.
