Us vs Them
It's a framework that we've likely used since the beginning of humanity. It's convenient because it condenses everything into absolutes. We are good, they are bad.

As our tribes have grown, the vectors through which we label and categorize people become more complicated, but we still try to work it around this simple idea - us vs. them. The groups, the tribes, the teams, can't possibly define others in a realistic manner - but we keep with it, because it's easy.

Maybe if we changed some of the vocabulary we could get past the divides. What would happen if the language about groups removed race, gender, incomes, job titles, political parties, etc.? How exactly would we define who the others are?

Maybe it would get too complicated. But maybe, it would force us to evaluate others through a more nuanced lens. After all, you're a them to someone.
