Historian Arnold Toynbee once famously said that “civilizations die from suicide, not murder.” Sometimes called ‘The Great Replacement,’ the uncontrolled invasion of Europe by Muslim freeloaders, rapists, and jihadists claiming to be ‘refugees’ over the past few years constitutes the biggest demographic transformation in history…and it’s about to accelerate.

Using this as a springboard, commentator Mark Steyn shows in a new video how Western Europe is already in the death throes of “demographic suicide” because couples are no longer having enough children. He then shows how a thriving Muslim population in Western Europe is well on its way to filling all the empty space.

Steyn explained how given the divergent birth rate between Muslims and post-Christian secularists, it will take only two generations for the current Muslim population (sitting at about 10-percent) to have as many grandchildren as post-Christian secularists (who currently make up the other 90 percent). This is due, he said, to Muslims having on average 3.5 children per couple compared to post-Christian secularists who have only 1.3 children per couple.
