In a 2009 speech railing against the Affordable Care Act, King said its contraceptive coverage threatened the birthrate of white Americans. "Preventing babies being born is not medicine. That’s not constructive to our culture and our civilization. If we let our birthrate get down below the replacement rate, we’re a dying civilization," King said.
During the 2016 Republican National Convention, King claimed that nonwhite peoples have not contributed to civilization as much as whites. "I would ask you to go back through history and figure out where are these contributions that have been made by these other categories of people you are talking about. Where did any other subgroup of people contribute more to civilization?” King said.
King has also found an ally in the far-right, anti-Islamic Dutch politician Geert Wilders. He endorsed Wilders in 2017, tweeting, "Wilders understands that culture and demographics are our destiny. We can’t restore our civilization with somebody else’s babies."
King has fought back against his critics who call him a white nationalist — by suggesting the term is not that offensive. Earlier this year, he told the New York Times: “White nationalist, white supremacist, Western civilization — how did that language become offensive? Why did I sit in classes teaching me about the merits of our history and our civilization?”
