Brewer was also a conspiracy theorist, claiming that 'The United States passed completely under the control of Roman Catholics, Jews and Communists under the reign of Franklin D. Roosevelt.' Weakly defending against his suspicions that he might be a bigot, Brewer wrote, 'Not all Jews are un-American, not all Catholics are disloyal to our ideals, but all Communists are un-American and anti-American. The Jews are internationalists, the Catholics are subject to a foreign power, and the Catholic system is contrary to American ideals.'
