“ Self-denial can lock women into a smug and critical condescension to other, less devout women.According to Appel, cult members develop..."an attitude of moral superiority, a contempt for secular laws, rigidity of thought, and the diminution of regard for the individual." A premium is placed on conformity to the cult group; deviation is penalized. "Beauty" is derivative; conforming to the Iron Maiden [an intrinsically unattainable standard of beauty that is then used to punish women physically and psychologically for failure to achieve and conform to it] is "beautiful." The aim of beauty thinking, about weight or age, is rigid female thought. Cult members are urged to sever all ties with the past: "I destroyed all my fat photographs!"; "It's a new me! ”
