In American Taliban: How War, Sex, Sin, and Power Bind Jihadists and the Radical Right, author Markos Moulitsas argues the Modern Conservative Movement (the Ann Coulters, Sarah Palins, Glenn Becks, Rush Limbaughs, etc.) lives by the very same set of values as the Taliban; their answer to everything is violence, they worship guns and biblical dogma, and view women as subordinate members of society just like the Taliban do. Having read the book, as well as notable chapters several times, I could not agree more.
However, to contribute to the discussion put forth by Moulitsas, I would also say the Modern Conservative Movement is a nationalist movement. Having been a history-major at Western Washington University, and having read Chris Hedges's book War is a Force that Gives Us Meaning, I had studied nationalism in various parts of Europe, and I do see similarities between the dogma put forth by pundits like Ann Coulter and other radical right-wingers.
Another word for nationalism is "Cultural Homogeneity", a term discussed by anthropologist Ernest Gellner. Under Cultural Homogeneity, a dominant culture takes power, and the minority cultures are either assimilated or excluded. When analyzing some of Ann Coulter's arguments, one will see just that. She divides Americans into two categories: The Republicans and the "others" (people she deems as "liberals" and "Democrats"). The perfect example is her case against widows of the 9/11/01 terrorist attack victims. She made an absurd case that the widows, who are also mothers, were somehow politicizing the terrorist attacks for their own profit and benefit. Coulter did this because the widows were a threat to the Republicans' reputation, so she goes on a personality-based attack campaign against them. They (the widows) were searching for the truth about America's national security, which Republicans have, in point of fact, been very irresponsible on. George Walker Bush's administration deliberately halted the CIA's investigations into Osama Bin Laden and Al Qaeda prior to the terrorist attacks. Coulter wants a media and a democracy controlled entirely by right-wing Republicans, so she works hard to discredit those who are opposed to them. She even accused them of working for John Kerry's presidential campaign in an attempt to make them look like her enemies, the liberal Democrats.
Coulter's work is similar to the policies of former Cluj Napoca Mayor Gheorghe Funar of Romania. Like Coulter, Mayor Funar divided people into two categories: The Romanian patriots and the "others" (mainly Hungarians). During his tenure as Mayor, he had referred to Hungarians as descendants of Barbarians, and sought to ban the singing of the Hungarian national anthem. He even ordered all city property to be painted the colors of the Romanian flag.
Fox Advertising (its given name is Fox News, but I refuse to call it that) is another good example of right-wing nationalist media. Hate-spewing bigots like Sean Hannity, Bill O' Reilly and Greta Van Susteren all go on personality-based smear campaigns against those who are opposed to Republicans. The best example is their smear campaign against former National Security Adviser Richard Clarke, who had criticized the Bush Administration for its negligent national security policies prior to 9/11/01. Fox's commentators (disguised as reporters) started calling Clarke a Democrat, which, of course, is pure nonsense. Another good example of right-wing nationalism is Greta Van Susteren's show. She covers stories purely from a Republican perspective, and she is just another Republican cheerleader who attacks Democrats by manipulating her viewers' fears. She and smarmy libelist Byron York were complaining about the "offensive signs" that the Wisconsin public-sector unions were holding up during their protests against Governor Scott Walker last year. Despite the fact that the protests were entirely peaceful, she tried to make them all look like violent criminals jeopardizing national security. Sean Hannity did the very same thing in his interview with the governor.
Glenn Beck is easily the most militant of the right-wing nationalists. He made up a nutty conspiracy that the Soros Foundation and the Obama Administration were behind the 2010 BP oil spill, and were going to instruct the Federal Emergency Management Association (FEMA) to set up concentration camps to stick white people in. Beck's fear mongering was so extreme that he inspired Byron Williams to plot an attack against the government, and Richard Poplawski's neo-nazi activism. In other words, he convinced his viewers, or better to call them his students, into thinking everyone around them was either on their side or with the "others". Glenn Beck treats his opponents the same way that Slobodon Milosevic treated the Muslims.
So that is it. The radical right are nationalists who want to live in an America run entirely by Republicans. I hope no one listens to them anymore.
