I read an article today, in which Mike Rowe rebuts a New York Times columnist about what it means to be a man. It's very nice, and rather snarky in that charming Mike Rowe way, and totally unnecessary. Hell, Mr, Rowe might agree with that assessment.
There is no such thing as a 'Modern Man', or a 'Man's Man'. You're either a responsible human being, or you're not. You're either a decent person, or you're not.
Unless you're a complete psychopath, I have to assume that an adult knows the difference between right and wrong. Additionally, most of us have some kind of moral compass.
It's very rare to find someone who doesn't know what thhe right thing to do is. It's more common to find people who know, and their conscience is eating at them for not doing it.
How hard is it to find North on a compass, for pete's sake? You know where it is.
