The men who are messing up their lives, their families, and their world in their quest to feel man enough are not exercising truemasculinity, but a grotesque exaggeration of what they think a man is. When we see men overdoing their masculinity, we can assume that they haven't been raised by men, that they have taken cultural stereotypes literally, and that they are scared they aren't being manly enough.
