Social sciences have the highest number of people who self-identified as Marxist back in 06. The rate was 17.6 as Marxist, 24.0 as radicals [1]. They've also been the worst field for the three decades of reproducibility crisis. You would have trouble convincing me that they aren't a fake, compromised "science" that ignores the scientific method to produce whitepaper propaganda.
