One of the great attractions of tribalism is that you don’t actually have to think very much. All you need to know on any given subject is which side you’re on. You pick up signals from everyone around you, you slowly winnow your acquaintances to those who will reinforce your worldview, a tribal leader calls the shots, and everything slips into place. After a while, your immersion in tribal loyalty makes the activities of another tribe not just alien but close to incomprehensible.
This is an important read, and important questions to ask ourselves.
