"When Nazis marched in Charlottesville in 2017, they chanted 'You will not replace us!' and, somewhat more clarifying, 'Jews will not replace us!'" says Jonathan Chait. "The terrorist who gunned down 51 people in Christchurch, New Zealand, used this slogan ('The Great Replacement') in his manifesto. (On Thursday night), Tucker Carlson appeared on a prime-time Fox News show to defend this theory, not only in substance but also by name. 'Replacement theory' imagines that an elite cabal, frequently described as Jewish, is plotting to “replace” the native white population with non-white immigrants, who will pollute and destroy the white Christian culture...Note that he is not merely arguing against illegal immigration. He is arguing against any immigration. Carlson proposes that any new U.S. citizen reduces the political power of the current population. When the Constitution was ratified, the United States had fewer than 4 million people, and 13 states. By Carlson’s standard, the last 200 years have been a continuous process of disenfranchisement of that original population. Immigration is a complex issue, and it is obviously possible to support restrictions on either legal or illegal immigration without being racist. But Carlson’s point implies that any immigration, legal or illegal, politically disempowers all Americans. Yet he’s not arguing for zero immigration. All he’s doing is framing immigration as some kind of zero-sum attack on the native population."
