Intellectual boundaries

This is harder to describe so let me start with a story about a family that I saw in counseling. This family had a single mother and 3 daughters. When the mother was confronted on something and started crying, all of her daughters cried. Similarly when one of the daughters started crying everyone in the family cried. The belief in this family was that if one cried then all must cry. That belief is an intellectual boundary. The intellectual boundary of the daughters had been crossed so that they believed what their mother told them about crying. In other words intellectual boundaries get crossed when a certain message or belief is told so many times, it becomes gospel truth in the family. Beliefs cannot be challenged but must be integrated instead. Intellectual boundaries are most commonly violated in families where to believe anything outside of the families beliefs gets met with criticism and ridicule. So for example if the family's religion is Methodist then anyone stating a Muslim belief would be met with ridicule. Another example is when a family is homophobic and one of the children realizes that he is homosexual. That family member gets met with criticism and hostility.
