The idiots are trying to legalize open hatred of gays. Imagine if student said he had dated someone of a different "race" and the counselor had said, "'god' put the waters there to separate the races, and you're mongrelizing the white race". How would that be any different than what the counselor did to a gay student?
If a lawyer refused to work in his client's best interests, if the lawyer compromised a defendant's rights at a trial, the lawyer would be disbarred. Why should counselors or pharmacists be allowed to violate the rights and security of others because of their own personal bigotry and ignorance?
