The ACLU works to ensure religious liberty by maintaining the wall of separation between church and state. The ACLU is not not anti-religion but believe that government must strictly avoid endorsing any religion, and should not be seen as expressing hostility towards religion or any religious sect. By ensuring government neutrality in religious matters, the First Amendment protects members of small or unpopular religions from being subjected to oppression or isolation from their government, which should be representing all and not taking sides on religious matters. The principle further protects the majority religion from being politicized by the government, and guarantees the right of all persons to practice their religion freely and without government interference.
