Update (Sept 6, 2017). I’m adding this CBS video about cooperation and finding commonality during Hurricane Harvey. “No one cares about the color or creed of their rescuer.”
One of humanity’s greatest assets as a species is our flexibility. We can live in a range of environments, and adjust to new social realities, diets, technologies, ideas, languages, etc. Our kids live in a world where communication across the globe is instantaneous, something that our ancestors would never have thought imaginable. Yet it’s completely normal for this generation. We adjust.
Still, nothing is cost-free. One drawback of our incredible plasticity and ability to hold a multitude of beliefs is an inherent risk for conflict. I say “avocado.” You say “mango.” People disagree on just about everything. What should we have for dinner? Are other people fully human? How should taxes be spent? Should baby boys wear pink? Are Nazis bad? Are there hats?
