Among the chapters of Indignant Heart recently made available by Libcom, Chapter 16 (“The Trotskyist Party”) is extremely important for its depiction of the strong current of racism that pervaded the Marxist parties, an under-acknowledged aspect of the history of the U.S. left. It’s not possible to discern any difference between the attitudes Denby faced every day from S.W.P. members and the racism prevalent in the larger society of the time. On the theoretical level, Denby exposes the fact that the Trotskyists did not even have an official party position on question of racial oppression in U.S. society. The unidentified speaker at the 1948 convention was, of course, C.L.R. James (the Johnson-Forest Tendency had rejoined the S.W.P. the previous year). The resolution put forth at the convention, the Revolutionary Answer to the Negro Question in the U.S., was published in Fourth International in December 1948 (under the byline J. Meyer). A revised version adopted by the party in 1950 (“Negro Liberation Through Revolutionary Socialism“) appears in Fourth International, May-June 1950. Both texts are available in the Marxists Internet Archive.
