Adding to its pattern of mainstreaming toxic extremism, Fox News regularly echoes and sanitizes the dangerous white supremacist conspiracy theory that non-white immigrants represent the threat of “replacement” to white populations. This racist talking point has already inspired massacres and hate crimes around the world.

On March 15, an avowed white supremacist shot and killed at least 50 Muslims and injured many others at two mosques in Christchurch, New Zealand. Prior to the massacre, the shooter allegedly wrote and promoted online a manifesto titled “The Great Replacement,” seemingly a reference to a popular white supremacist conspiracy theory fearmongering about white populations being replaced in majority-white countries due to demographic changes. The same sentiment was echoed during a 2017 white supremacist rally in Charlottesville, VA, in which white supremacists holding torches chanted, “You will not replace us.”

Proponents of the conspiracy theory often scapegoat immigration as the central cause by which white people are being “replaced,” and they blame politicians and elites, saying they are intent on changing the demographics of predominantly white nations to dilute the political power of white populations. A mass shooting believed to be deadliest anti-Semitic attack in American history -- in which a gunman opened fire in October 2018 inside of a Pittsburgh, PA, synagogue, murdering 11 people -- was also motivated by the replacement conspiracy theory, with the alleged shooter accusing Jewish people of bringing in “invaders" to “kill our people."

While the replacement conspiracy theory has long been a mainstay in white supremacist circles, Fox News has been mainstreaming the concept by consistently fearmongering about the threat of replacement via changing demographics in the United States.
