An Idaho Republican is backing a bill which would allow state-licensed professionals to discriminate against gays.

Idaho Rep. Lynn Luker's bill would allow professionals to refuse service or employment based on their religious beliefs.

“This bill prohibits government from denying, revoking or suspending any professional or occupational license or registration based upon actions involving the exercise or expression of sincerely held religious beliefs,” House Bill 426's summary reads.

In speaking with CBS affiliate KBOI, Luker cited an Oregon case involving a baker and a New Mexico case involving a photographer as a catalyst for his proposal. In both of those cases, the business owners refused to serve a gay couple in violation of the state's anti-discrimination laws.

Idaho's Human Right Act, however, does not prohibit discrimination on the basis of sexual orientation and Republican lawmakers have blocked efforts to update the law.

“This is pre-emptive,” Luker said. “The issue is coming, whether it's 10 years, or 15 years, or two years.”

The Christian conservative Cornerstone Family Council has endorsed Luker's proposal.

“The free expression of religious freedom is no longer understood for what it was intended,” said Julie Lynde, the group's executive director. “There's a double standard against people of traditional religious faiths.”

Monica Hopkins, executive director of the American Civil Liberties Union of Idaho, criticized the measure: “This is a solution searching for a problem.”
