Religion gives Ms Keeton, the license to hate anyone or any group of people she chooses. We are not a Christian theocracy in America. There are Jews, Muslims, Atheists, Satan worshippers, Wiccas, Buddhists, and a whole array of religions that Keeton will encounter if she decides to become a counselor in the United States. Keeton must adhere to the ethics of the profession she trains in. If she wants to only cater to those of her beliefs, she should become a counselor for her church. She shouldn't expect to work for an agency or school that follows APA and ACA guildelines.

Thus, mental health professionals and researchers have long recognized that being homosexual poses no inherent obstacle to leading a happy, healthy, and productive life, and that the vast majority of gay and lesbian people function well in the full array of social institutions and interpersonal relationships.

The longstanding consensus of the behavioral and social sciences and the health and mental health professions is that homosexuality per se is a normal and positive variation of human sexual orientation.
