You will know the tribes by their bumper stickers. Those watch-your-back talismans affixed to our minivans. We’re social animals, desperate for extended families, but tribalism which served us well in ancient times now splinters a humanity hungry to be whole. The myth of the staunch individualist ignores accomplishments of our collective will, yet individualism is precious, and herd mentality both dangerous and dull. Think of that frightful tribe, motivated by unconditional loyalty, its mindless chants filling stadiums in crude rituals of domination. I’m speaking, of course, about Green Bay Packers fans.

Thankfully, Vikings fans are a pale imitation of their namesakes from Scandinavia, those longboat marauders, as vicious and cruel, it is alleged, as many a hedge fund manager. But the Vikings got over it. They traded their battle axes for Volvos and social democracy. Instead of kidnapping they’re exporting cheap furniture, because Us against Them will get you only so far.

A handful of close friends is a blessing beyond measure. How do we hold onto that without circling the proverbial wagons? How can tribes expand and blend like living Venn diagrams without falling into in-group ethics? How do we “coexist” as one tribe’s bumper sticker suggests? “Don’t Tread On Me,” says another’s, twisting the sentiment of revolution for reactionary effect. A rattlesnake, poised to strike, illustrates the theme. Along with this less-than-veiled threat, drivers approaching our blindside must be warned we are insured by Smith and Wesson, and deputized for vigilante justice. Tailgate at your own risk, and don’t step on my snake.
