Murray has been accused of promoting several far-right conspiracy theories. In "Ethnic and Racial Studies" Ed Pertwee argued that Murray's work is an "extemporization of the basic theme" of the Eurabia conspiracy theory as developed by Bat Ye'Or in the 2005 book "Eurabia: The Euro-Arab Axis". Ilgın Yörükoğlu of the City University of New York remarked that by promoting the Eurabia theory while being a best-selling author, Murray had provided the "emotional energy" for the conspiracy theory. Murray has also been accused of promoting the related far-right Great Replacement conspiracy, which contends that the developed world is being deliberately overwhelmed with non-white immigration as part of an elite conspiracy. Murray's book has also drawn scrutiny for "remodelling" the far-right Cultural Marxism conspiracy theory, though Murray has indicated that he personally dislikes the term "Cultural Marxism".
