Quoted in War and Conflict Quotations: A Worldwide Dictionary of Pronouncements from Military Leaders, Politicians, Philosophers, Writers and Others (1997) by Michael C. Thomsett and Jean F. Thomsett
Paraphrased variant: "I doubt if the oppressed ever fight for freedom..."
Context: It is doubtful if the oppressed ever fight for freedom. They fight for pride and power — power to oppress others. The oppressed want above all to imitate their oppressors; they want to retaliate.
