You’re mixing up cranks and bigots. Bigots tend to get banned because they’re harmful. Cranks tend to exclude themselves on principle.
The term “crank” is usually used as a pejorative, but cranks can sometimes be beneficial. Richard Stallman is the prototypical example of a Free Software crank. Definitely annoying, but also definitely a net benefit to all of us.
