To her, conscience must submit to an external authoritarian Divine standard, which is applicable to all people. There is no personal choice. Dr. Laura appeals to our human tendency to be told clearly what is right or wrong and not make any decisions for ourselves. Such is the reason why fundamentalist religions and cults are also attractive to thousands of people. There is no personal choice.
Life is much too complex today for simplistic solutions.
I believe it is important for us to struggle with conflicting options, to consider contradictory alternatives in every ethical situation. Indeed, such an approach is far more demanding than Dr. Laura's but ultimately, I believe, it is more spiritually satisfying and growth-producing.
