"The population of Muslims and Christians is growing day by day. To rein in this, Centre will have to impose emergency, and Muslims and Christians will have to be forced to undergo sterilisation so that they can't increase their numbers," vice president of All India Hindu Mahasabha Sadhvi Deva Thakur said, according to India Today Thakur also urged Hindus to have more children and increase their population so as to have an effect on the world.The politician, however, did not just restrain herself to forcible sterilisation and claimed idols of Hindu gods and goddesses should be placed in mosques and churches.Thakur also came out strongly in support of installing a statue of "patriot" Nathuram Godse in Haryana.A census data in January this year on the population of religious groups in India showed a 24% rise in the Muslim population between 2001 and 2011, with the community’s share of total population rising from 13.4% to 14.2% over the 10-year period.Further, according to Pew Research Center’s projections released earlier this month, Muslim and Christian populations could be nearly equal by 2050, with Islam expected to be the fastest-growing faith on the planet.The Pew Research Center’s religious profile predictions assessed data from around the world on fertility rates, trends in youth population growth and religious conversion statistics.According to the report, “Over the next four decades, Christians will remain the largest religious group, but Islam will grow faster than any other major religion.”The authors predicted there will be 2.76 billion Muslims on the planet by then, and 2.92 billion Christians. Those figures would correspond to about 29.7% and 31.4%of the world population, respectively.
