I like Lenin's quote "A slave who is aware of his servile position and fights against it is a revolutionary. A slave who is unaware of his slavery and vegetates in a silent, unconscious and wordless slave life is simply a slave. A slave who salivates when he complacently describes the delights of slave life and admires a kind and good master is a slave, a cad." V.I. Lenin, "In memory of Count Heyden". // PSS vol.16 p.40
Also see The Military Programme of the Proletarian Revolution regarding slaves using weapons.
