Politically Correct or "PC" thinking is a potent force, operating at all levels of education in the U.S. Even preschool play is not immune from censorship of traditional tunes and gender-specific toys. From super-heroes to imaginary shoot-outs, from holiday celebrations to board games, teachers run the risk of offending colleagues and parents. Society expects educators to inculcate its values, even when these values are not congruent: for example, we value individual freedom and we value conformity; we value competition and altruism; we value immigration and high fences.
