Mississippi recently passed a “religious freedom” law designed to provide legal cover for those who wish to discriminate against gays and lesbians. The law is quite specific, allowing government clerks to refuse to issue marriage licenses to same-sex couples and protecting businesses that refuse to serve them. The U.S. Supreme Court’s 2015 decision legalizing same-sex marriage set off a spate of proposals that serve no purpose except bigotry — laws that prop up prejudice with Scripture. The giveaway in several of those bills is this: They allow for-profit businesses to claim to have religious beliefs and to refuse service on that basis.
