Yeah. I mean, I get it. Communities are formed around shared values and beliefs. If they weren’t, those communities would fracture and fall apart and they wouldn’t be communities anymore; and humans die when they’re alone. So changing your belief systems or admitting you’re wrong has an actual, measurable impact on you–on a biological level–making you feel like you’re going to die alone and your genetic line will end. It feels like an existential threat. It’s scary.

But it’s worth it; and in this big, diverse world, it’s possible to find a new community now, where it hasn’t been for most of our species’ history. We’ve grown to the point where we don’t have to follow that deep-brain worry anymore.

Some people don’t agree.
