In India class and class overlap this was neither taken note by Coms and nor by identity politics. If we take Engel's notion of Marxist as one who reacts to a situation as Marx would have, not the one who quotes him or Marx, Ambedar is a Marxist. Contrary to Marx's expectations colonialism was not interested in smashing the Asiatic Mode but used it for plunder. There was no real bourgeois democratic movement against the class qualification that was smashed in Europe during Renaissance. Ambedkar reacted, in my opinion, as Marx would have in the situation.
