"The victims of the Pakistani repression in East Bengal in 1971 (of whom the big majority were Hindus, while the Bengali Muslims too were killed for anti-Hindu reasons, viz. for being "half-Hindu renegades"), like those of the Sultanate and Moghul regimes, have never been properly counted; careerwise, it is suicidal for a scholar to calculate the magnitude of Islam's crimes against humanity. The figure of 3 million is probably too high, but as it was given by a Muslim secularist (Bangladesh founder Mujibur Rahman), and as the secularists themselves have thrown their full weight against a proper study of the magnitude of Islamic massacres of Hindus, they cannot fault us for provisionally sticking to it."
