“We have a saying in the union: "If a fellow looks like a duck and quacks like a duck and walks like a duck, the possibility is that he is a duck." That is the way with a Communist. If the guy does everything that the party does, the prospects are very good that he is a party member or fellow traveler.”

Walter Reuther (1907–1970) Labor union leader

Regarding Communists; hearing before the Senate Committee on Labor and Public Welfare (1953)

Michael J. Behe (1952) American biochemist, author, and intelligent design advocate
