[9] The scholars Patrik Hermansson, David Lawrence, Joe Mulhall, and Simon Murdoch noted that in the "press and broadcast media", the term had been "used to describe everything from hardcore Nazis and Holocaust deniers, through to mainstream Republicans in the US, and right-wing populists in Europe".
They noted that its "core belief is that 'white identity' is under attack from pro-multicultural and liberal elites, and so-called 'social justice warriors' (SJWs), who allegedly use 'political correctness' to undermine Western civilisation and the rights of white males".
[16] The anti-fascist researcher Matthew N. Lyons defined the alt-right as "a loosely organized far-right movement that shares a contempt for both liberal multiculturalism and mainstream conservatism; a belief that some people are inherently superior to others; a strong Internet presence and embrace of specific elements of online culture; and a self-presentation as being new, hip, and irreverent".
Lastly, Tait noted that unlike the "moral opprobrium" of the Ku Klux Klan and American Nazi Party, "the early alt-right centered on flagship publications was, to some extent, invested in a kind of white nationalist respectability politics.
"[18] The Southern Poverty Law Center defined the alt-right as "a set of far-right ideologies, groups and individuals whose core belief is that 'white identity' is under attack by multicultural forces using 'political correctness' and 'social justice' to undermine white people and 'their' civilization".
", including changing demographics, the rise of the Internet and social media giving a significant platform to more extreme right-wing voices that were previously marginalized by "responsible conservative gatekeepers", the perceived failure of the war on terror led by neoconservatives, the Obergefell v. Hodges Supreme Court decision that legalized same-sex marriage and undermined social conservatism, the 2008 Great Recession that undermined conservatives' support of the free market, and men with certain beliefs about gender roles "feeling traditionally male spaces were being eroded."
Both opposed neoconservatism and expressed similar positions on restricting immigration and supporting an openly nationalistic foreign policy; however, unlike the alt-right, the paleoconservatives were typically closely aligned to Christianity and wanted to reform the conservative movement rather than destroy it.
[46] Many senior alt-rightists previously considered themselves libertarians,[47] and right-libertarian theorist Murray Rothbard has been cited as a particular link between the two movements due to his staunch anti-egalitarianism and support for ideas about differing IQ levels among racial groups.
[53] According to Dean, in the 1990s, there were "alt-right" Usenet groups that consisted of fringe libertarians, anarcho-capitalists, and fans of American writer and philosopher Ayn Rand, who advocated for the abolition of the state in favor of private property and markets.
[86] Although there had previously been a strong left-libertarian contingent to these online spaces, there was a gradual rightward turn in chan culture centred on 4chan's politics board, /pol/, during the early-mid 2010s, with the fundamentalist approach to free speech contributing.
[18][90][91] According to the journalist David Neiwert, Gamergate "heralded the rise of the alt-right and provided an early sketch of its primary features: an Internet presence beset by digital trolls, unbridled conspiracism, angry-white-male-identity victimization culture, and, ultimately, open racism, antisemitism, ethnic hatred, misogyny, and sexual and gender paranoia".
[14] Other prominent alt-rightists included Brad Griffin, a member of the neo-Confederate League of the South who founded the Occidental Dissent blog,[100] Matthew Heimbach, who established the Traditionalist Youth Network in 2013,[101] and Andrew Anglin, who launched the Daily Stormer website—named after the Der Stürmer newspaper active in Nazi Germany—in 2013.
[103] While some of the websites associated with the alt-right—like The Daily Stormer and the Traditionalist Youth Network—adopted neo-Nazi approaches, others, such as Occidental Dissent, The Unz Review, Vox Popoli, and Chateau Heartiste, adopted a less extreme form of white nationalism.
[129] McInnes clarified his understanding of the difference between the alt-right and alt-lite by explaining that while the former focused on the white race, the latter welcomed individuals of any racial background who shared its belief in the superiority of Western culture.
[130] In June 2015, billionaire businessman Donald Trump announced plans to campaign to become the Republican nominee for the 2016 presidential election, attracting the interest of alt-rightists as well as from white nationalists more broadly, neo-Nazis, KKK groups, and the Patriot movement.
[168][169] While aware that Trump would not pursue a white nationalist agenda, the alt-right hoped to pull him further to the right, taking hardline positions that made him look more moderate, and thus shifting mainstream discourse rightward.
[177] In April 2017, many alt-rightists criticized Trump's order to launch the Shayrat missile strike against Syrian military targets; like many of those who had supported him, they believed he was going back on his promise of a more non-interventionist foreign policy in the Middle East.
An African-American man, DeAndre Harris, was assaulted by demonstrators, while Richard W. Preston, an Imperial Wizard for the Maryland-based Confederate White Knights of the Ku Klux Klan, fired a gun towards counter-protesters.
This happened for multiple reasons, including the backlash of the Unite the Right rally, the fracturing of the movement, more effective banishment of hate speech and harassment from major social media websites and widespread opposition by the American population.
[227] That year, Heimbach was arrested for the battery of his wife and father-in-law, resulting in the dissolution of his Traditionalist Workers Party,[228][227] while Anglin went into hiding to avoid a harassment lawsuit, and Spencer canceled his speaking tour.
[272] The prominent alt-rightist Greg Johnson suggested that it would come about after white nationalists became the dominant force in U.S. politics, at which point they would deport all illegal migrants, before encouraging all other people of color to emigrate.
[322] Others on the alt-right oppose Christianity entirely, criticizing it for its Jewish roots, for being a universal religion that seeks to cross racial boundaries, and for encouraging what they see as a "slave morality" that they contrast with perceived ancient aristocratic values.
[322][328] White evangelical leaders of the Southern Baptist Church have angered the alt-right by expressing support for refugees entering the U.S., calling for measures to help undocumented migrants gain legal status, and urging members not to display the Confederate Battle Flag.
"[355] The animal studies scholar Vasile Stănescu suggested that this notion drew upon the 19th-century pseudoscientific idea that Northern Europeans had become biologically superior to many other human populations, because they consumed high quantities of milk and meat products.
In what it called "Operation: Filthy Jew Bitch",[421] The Daily Stormer encouraged its followers to send abuse to the British Member of Parliament (MP) Luciana Berger, who is Jewish; images sent to her featured a yellow star on her head, accompanied by the hashtag "Hitlerwasright".
Tait also said "that a large segment of the movement was composed of young, male YouTubers and memelords who advanced misogynistic, anti-liberal, antisemitic, and often racist ideas as they shitposted pro-Trump or anti-progressive memes under absurd pseudonyms".
[18] On interviewing young alt-rightists, Hawley noted that many revealed that they embraced far-right politics in response to the growing racial polarization of the Obama era; in particular, the public debates around the shootings of Trayvon Martin and Michael Brown, and the rise of the Black Lives Matter movement.
[443] Drawing comparisons with the tale of The Boy Who Cried Wolf, the commentator Angela Nagle also suggested that "the hysterical liberal call-out" culture of the 2010s, in which "everyone from saccharine pop stars to Justin Trudeau [was called] a 'white supremacist' and everyone who wasn't With Her a sexist" made it more difficult for people to recognize when a far-right movement really emerged online.
[462][463] In August 2019, the self-described alt-right member James Patrick Reardon of New Middleton, Ohio was arrested, accused of threatening violence against local Jewish communities; an arsenal, or weaponry, was found in his home.
[54] Responding to Trump's use of the term, various commentators criticised the use of "alt-left", claiming that it was neither created nor adopted by leftists but had been designed by right-wingers and/or centrist liberals to smear left-wing protesters by suggesting a false equivalence between the alt-right and their opponents.
