"Regressive left" (also formulated as "regressive liberals") is a political epithet, used as a pejorative to describe a section of left-wing politics who are accused of paradoxically holding reactionary views by their tolerance of illiberal principles and ideologies, particularly tolerance of Islamism, for the sake of multiculturalism and cultural relativism.
British anti-Islamism activist Maajid Nawaz used the term in 2012 in his memoir Radical: My Journey out of Islamist Extremism to describe "well-meaning liberals and ideologically driven leftists" in the United Kingdom who naïvely and "ignorantly pandered to" Islamists and helped Islamist ideology to gain acceptance. In a 2015 video presentation on the Internet forum Big Think, Nawaz elaborated on the meaning of the term, saying that it describes "a section of the left" that has "an inherent hesitation to challenge some of the bigotry that can occur within minority communities ... for the sake of political correctness, for the sake of tolerating what they believe is other cultures and respecting different lifestyles".
Political talk-show hosts such as Bill Maher and Dave Rubin, as well as New Atheist writers like Sam Harris and Richard Dawkins are among those who have used the term.
In 2007, Maajid Nawaz renounced his previous association with the radical Islamist group Hizb ut-Tahrir in favor of secular Islam. He is co-founder and chairman of Quilliam, a counter-extremism think tank based in London that seeks to challenge Islamist ideology.
