"It cannot be denied that this is happening in Bengal. 30% of the total population there are Muslims (some say 23%, some 25%, but 30% if the voting figures are to be considered). The border districts adjoining Bangladesh, such as Nadia, Dinajpur, Murshidabad, Malda, and a large part of South 24 Parganas, all have become completely Muslim dominated."
