The ACLU protects the freedom to practice any religion, or no religion at all. We work to prevent an excessive entanglement of government and religion, as the framers of our Constitution intended. We advocate for the free exercise of religion, including the rights of Muslims and Jews to wear religiously appropriate headgear, for Jehovah’s Witnesses to refrain from saluting the flag and accepting medical treatment, and for the Santeria to engage in ritual animal sacrifice. We oppose government endorsements of religion, including Latin crosses displayed on government buildings, prayer at public school graduation ceremonies, and the statutory command that school children pray or reflect during a daily moment of silence. We also oppose government aid to religious activity, including tuition tax credits for religious education, legislative earmarks for religious institutions, and special treatment for and direct sponsorship of the Boy Scouts (which practices religious discrimination).
