religious persecution of dalits

Islamic rulers enjoyed their stay in India using our capacity of wealth creation but kept on inflicting deep wounds in the structure of our prosperous and open society by converting it into patently hierarchical and strictly patriarchal structures to suit their habit, tradition and culture of religious expansionism. Dalits came into being during this period historically. Social scientists have until now not been allowed by the liberal-historians to do research on the emergence of Dalit and mahadalit communities during a period when actually Brahmins were being religiously persecuted continuously, were killed on a massive scale and were humiliated at the will of the medieval rulers.
