Although his Oklahoma family had voted Democratic, McIntire eventually became a conservative Republican. Before and during World War II, McIntire opposed Nazi totalitarianism and anti-semitism, and afterwards he became a champion of anti-Communism and especially one who attacked Communist control of religion in the Soviet Union. McIntire argued that although America had once honored God and freedom, it was in danger of losing its heritage. On his radio program, McIntire often repeated the slogan, "Freedom is everybody's business, your business, my business, the church's business, and a man who will not use his freedom to defend his freedom, does not deserve his freedom."
