Thanks for your detailed reply. High caste "Hindus" seem to take to communism just like Jews (Marx, Engles, etc). Communists in Bengal still celebrate Durga Puja - I don't know how that makes intellectual sense, though it does make political sense.
Prachananda was neutral till he came to India and studied in the bastion of communism, Jawarharlal Nehru University in Delhi.
Indeed. I have noticed that too. I think it has to do with guilt, primarily. And notice how all these upper caste commie leaders come from really orthodox, priestly families. I seriously think they are brainwashed in thinking they and their castes being the reason of all the suffering. Taking directly from Buddhist guilt-trip idealogy. No wonder Siddhartha Gautam suffered a jolt when he, as a prince, saw all the poverty around him. And thought it was all because of attachment. Typical then, typical now.
