Carlson is a frequent critic of immigration.[79] Carlson has been accused by Erik Wemple of The Washington Post and by writers for Vox of demonizing immigrants, both those who immigrated to the U.S. legally and illegally.[80][81][82][83]He has opposed demographic changes in the United States, writing that the demographic change seen in Hazleton, Pennsylvania, which saw Hispanics go from a small minority to a majority over a 15-year period, is "more change than human beings are designed to digest".[83] In 2018, Carlson suggested that mass immigration makes the United States "dirtier", "poorer" and "more divided".[84][85] In response to criticism of this, he has said that "we're not intimidated" and "we plan to try to say what's true until the last day. And the truth is, unregulated mass immigration has badly hurt this country's natural landscape".[86] Of illegal immigration, Carlson said in May 2019, "The flood of illegal workers into the United States has damaged our communities, ruined our schools, burdened our healthcare system and fractured our national unity."[71]
Heidi Beirich of the Southern Poverty Law Center said that "Carlson probably has been the No. 1 commentator mainstreaming bedrock principles of white nationalism in [the US]," and accused him of promoting the white genocide conspiracy theory, the idea that white people are under attack by minorities and immigrants.[87] Anti-Defamation League's Jessica Reaves has compared Carlson's defense of the nuclear family to white supremacist anti-immigrant rhetoric.[88]
According to CNN, Business Insider, Vox and GQ, Carlson's show has promoted and echoed white supremacist discourse.[89][90][91][92] Neoconservative pundit Bill Kristol described the views Carlson expressed on his show as "ethno-nationalism of some kind";[93] Carlson responded that Kristol had "discredited himself years ago."[94] Carlson has denied being a racist and has said that he hates racism.[3]
Andrew Anglin, founder of the neo-Nazi website The Daily Stormer, referred to Carlson as "literally our greatest ally", and to his show as "basically 'Daily Stormer: The Show'".[95] According to independent analysis, Carlson has been featured on 265 articles published by The Daily Stormer during a two-year period.[95] Carlson has also been repeatedly praised by members of Identity Evropa, a major North American neo-Nazi organization.[96]
In call-in segments Carlson made from 2006 to 2008 on the radio show of Bubba the Love Sponge, Carlson stated that Iraq was not worth invading because it was a country made up of "semiliterate primitive monkeys" who "don't use toilet paper or forks." He also criticized "lunatic Muslims who are behaving like animals", and said that any presidential candidate who vowed to "kill as many of them as [they] can" would be "elected king". Recordings of these segments were released online on March 2019 by the progressive non-profit Media Matters for America. The Washington Post labelled these comments racist.[97] Carlson also made demeaning remarks towards women, made light of rape, defended then-alleged criminal Warren Jeffs and used homophobic slurs.[98][97] Carlson declined to apologize for his comments.[99]
In 2018 and 2019, the show was the target of an advertiser boycott. Advertisers began leaving the show after Carlson's said that U.S. immigration make the country "poorer, dirtier and more divided." According to Fox News, the advertisers only moved their ad buys to other segments.[100] By early 2019, the show had lost at least 26 advertisers.[101][102]
When Mitt Romney condemned then-candidate Donald Trump after Trump evaded questions about David Duke’s support,[103] saying it was a "disqualifying and disgusting response [...]. His coddling of repugnant bigotry is not in the character of America", Carlson criticized Romney. Carlson said "Obama could have written" that.[104]
Carlson concluded his July 9, 2019 Tucker Carlson Tonight episode with a 3-minute monologue about Rep. Ilhan Omar (D-MN); he criticized Omar for being un-grateful to the United States, where she had been granted asylum, and called her "living proof that the way we practice immigration has become dangerous to this country." His monologue was described by The Guardian as "scathing", "racially loaded", and "full of anti-immigrant rhetoric".[105]Congresswoman Omar responded immediately on Twitter, saying that "advertisers should not be underwriting this kind of dangerous, hateful rhetoric."[106] In their July 10 article on the incident, The Daily Beast said that, mainly because of "right-wing attacks that have then been amplified by members of Congress and the president", Omar has been receiving death threats since she was elected to Congress.[107] According to the article, while Carlson "has devoted numerous segments" of his show to criticizing her, this time Carlson "took his anti-Omar stance even further."[107]
Days after the 2019 El Paso shooting which was committed by a man who released an anti-immigrant manifesto complaining of a "Hispanic invasion", Carlson described white supremacy as a "hoax" and "a conspiracy theory used to divide the country and keep a hold on power". He asked rhetorically, "the combined membership of every white supremacist group in America - would they be able to fit inside a college football stadium?"[108][109][110] According to The Washington Post, "Carlson’s argument is belied by many experts and seemingly contradicted by a recent wave of deadly attacks by men motivated by those views."[111]
