They could be, but there is a much lower threshold to manipulate people who are close-minded. Almost everyone I've encountered who repeats racially charged headlines is LESS likely to have much personal experience with the people they feel so strongly about, even to the point of avoiding encounters with those people.

Close minded means you are not open to new impulses.If they are close minded they by definition is bound by something old which should make them harder to manipulate.

A person that does the creative arts is generally very open minded.
