You don’t evolve past being a cowboy. Being a cowboy is the pinnacle of evolution. Once you’re at cowboy, there’s nowhere to go but down. Cowboys don’t look for fights, but they don’t run away from them either. They do what they have to do, when they have to do it. And they usually have to do it alone, because everyone wants Black Bart’s gang out of town, but no one wants to walk down the street alongside the sheriff and get shot doing it.
You don't have to read the article, which is political, to appreciate the sentiment about cowboys. I think that's why so many women love cowboy heroes—that simple realization that a cowboy does what needs to be done, as efficiently as possible, even when the odds and the crowd are against him.
