Men who spend no time training the metaphorical muscle of masculinity like to believe that they would be able to step in and be a hero if some extreme scenario demanded it, but this is for the most part a fantasy sold to them by the entertainment industry. Men who work call centers and spend all of their free time watching television or playing video games are not going fight off any man who has experience with violence. They're not going to save the world, or their girlfriends, or even themselves.
