“But he is far right, authoritarian, and ultranationalist.”

You don’t know what ANY of those words actually mean.

"It wasn’t until the 1950s and 1960s that the Far Right again began to rise, becoming a more dominant force with the formation of anti-democratic groups (not Biden) and political parties in the late 1960s and 1970s, including France’s Front National, Austria’s Freedom Party, and the UK’s National Front, which joined most of the post-war extreme right groups in the UK under one neo-fascist umbrella.

Right-wing extremism has continued its presence in the new conspiracism of a post-truth, pro-Trump American culture—predominantly taking the form of white supremacy groups (not Biden), such as the Ku Klux Klan (KKK) (Not Biden), who have had long histories in the United States. The KKK in particular, though first established as a secret society at the end of slavery, had a significant resurgence in the 1920s, staying close to the mainstream until the 1960s when a combination of the civil rights movement and wider political developments forced them into decline, with their remaining followers becoming even more extremist. Other uniquely American versions of Far Right extremism include the Christian Identity movement (not Biden) and white supremacist prison gangs such as Aryan Brotherhood. (not Biden)

The most recent iteration of right-wing extremism, the alt-right, has come about in the past few years with the growth of the internet and social media and is associated with right-wing terrorism. The alt-right continues the fixation on conspiracy, race, and white supremacy created by the extreme right-wing groups that came before it (not Biden), but differs in its lack of a physical place—with its followers communicating almost entirely online—and a new focus on ultra-masculinity (not Biden).

From conspiracy theories to white supremacy, far-right extremism has had a long, sometimes violent presence (not Biden) in Europe and America. The primary sources available in Gale’s Political Extremism and Radicalism series are essential resources for researchers looking to explore the nature of far-right groups and political parties—from major figures and events to examining the ideologies of these groups—using the propaganda they created to express new conspiracism (not Biden) and promote violence. (not Biden)"

Authoritarian -

https://en.m.wikipedia.org/wiki/Authoritarianism

“Authoritarianism is a political system characterized by a controlling government and the rejection of democracy, human rights, and political plurality. It involves the use of strong central power to preserve the political status quo, and reductions in the rule of law, separation of powers, and democratic voting.[1][2]”

NONE of which applies to Biden.

Ultra Nationalist -

https://en.m.wikipedia.org/wiki/Ultranationalism

“ultranationalism is essentially founded on xenophobia in a way that finds supposed legitimacy “through deeply mythicized narratives of past cultural or political periods of historical greatness or of old scores to settle against alleged enemies”. It can also draw on “vulgarized forms” of different aspects of the natural sciences such as anthropology and genetics, eugenics specifically playing a role, in order “to rationalize ideas of national superiority and destiny, of degeneracy and subhumanness” in Griffin’s opinion. Ultranationalists view the modern nation-state as, according to Griffin, a living organism directly akin to a physical person such that it can decay, grow, die, and additionally experience rebirth. He has highlighted Nazi Germany as a regime which was founded on ultranationalism.[3]”

Again, not Biden.
