alt Hacker NewsI think parent commenter is using "men" in a manner similar to mensch, as in "a person of integrity and honor" [1]. In other words, "look around and notice nobody is taking responsibility, and choose to be the person who lifts others up." Or something.
It's a weird way to phrase it, in my opinion, especially in this era where we are generally avoiding ambiguously gendered collective nouns... but I'm pretty sure that's the gist. Or, at least, it's how I read it.
