Many Jews try not to read salacious material, because we wish to become ever holier. However, no one can control what we buy and eat except ourselves. If we want to be holy, we must practice self-discipline, not rely on other people to force us into patterns of behavior. Rabbis offer guidance, when we request it. Rabbis are primarily teachers.
Cults often impose an unbalanced, unhealthy diet on their members.
Someone might argue that Judaism imposes a kosher diet on its members. Kosher food, however, is not unhealthy. It is simply a special way of preparing regular food. Cults, however, generally force on their members a diet high in one food type, so as to impair their health and inhibit their faculty of clear thought. Furthermore, Judaism takes into account medical needs.
