That's not the law's intent, of course. Arizona's proposed new law, like the ones in Kansas and Idaho, is about legalizing discrimination against gays and lesbians. But in an effort to hide the anti-gay prejudice behind their "religious liberty" bill, Arizona lawmakers have worded it so vaguely that it empowers anyone of any faith to discriminate against anyone for any reason—provided, of course, that the person doing the discriminating remembers to cite their sincerely held religious beliefs as a justification.
Mother Jones reports on this sudden wave of anti-gay legislation.
I don't remember where I read it but this is a good idea: these laws should include a provision requiring business owners who wish to access their "protections" to publicly post signs in their windows and on their websites listing the types of people they refuse to serve. That might prompt some hateful Christianists to think twice. Because then they wouldn't just be losing the business of the odd gay couple they got to turn away in a fit of self-righteous assholery. They would also be losing the business of straight people who don't want to patronize businesses that discriminate against their gay and lesbian friends, neighbors, and family members.
UPDATE: Et tu, Maine?
