I see this style of framing a lot and it always seems like turtles all the way down to me:

- Smart people recognize that some people are stupid

- No, real smart people recognize that behaviors are stupid, not people

- No, real smart people don't label others, including calling themselves smart, based on a small sample of observed behaviors. They leave the dichotomy behind.

- Wait, you still called yourself smart...?

- You are all wrong, all labels are generally meaningless and unhelpful in describing dynamic people in a dynamic world, though let's not be dogmatic about it, sometimes a dolt is a dolt and a genius is a genius
