Humanists and other Americans who care about religious freedom should be upset by the continuation of an effort by some Republicans in Congress to use religious freedom as an excuse to participate in bad behavior towards other Americans, either because of their sexual orientation, gender identity, sexual history, or other unimportant factors. At the end of the day, these Republicans still have yet to learn the fundamental lesson that can be gleaned from America’s religious diversity and constitutionally mandated pluralism: that religious freedom should be used as a shield, and not as a sword to attack others who believe, look, or love differently than they do.
