Right-wing politics
Although the right-wing originated with traditional conservatives, monarchists, and reactionaries, the term extreme right-wing has also been applied to movements including fascism, Nazism, and racial supremacy. From the 1830s to the 1880s, there was a shift in the Western world of social class structure and the economy, moving away from nobility and aristocracy towards capitalism. This general economic shift toward capitalism affected centre-right movements such as the British Conservative Party, which responded by becoming supportive of capitalism. In the United States, the Right includes both economic and social conservatives. In Europe, economic conservatives are usually considered liberal and the Right includes nationalists, nativist opposition to immigration, religious conservatives, and historically a significant presence of right-wing movements with anti-capitalist sentiments including conservatives and fascists who opposed what they saw as the selfishness and excessive materialism inherent in contemporary capitalism.
Regressive left
"Regressive left" (also formulated as "regressive liberals" and "regressive leftists") is a neologism and political epithet, used as a pejorative to describe a section of left-wing politics who are accused of holding paradoxical, reactionary views by their tolerance of illiberal principles and ideologies, particularly identity politics (emphasis on group identities like race and gender, rather than on the individual), and opposition to free speech for the sake of multiculturalism and cultural relativism.
