I've seen several people on Less Wrong recommend Mencius Moldbug's writings, and I've been curious about how he became so popular here. He's certainly an interesting thinker, but he's rather obscure and doesn't have any obvious connection to Less Wrong, so I'm wondering where this overlap in readership came from.
[EDIT by E.Y.: The answer is that he's not popular here. The 2012 LW annual survey showed 2.5% (30 of 1195 responses) identified as 'reactionary' or 'Moldbuggian'. To the extent this is greater than population average, it seems sufficiently explained by Moldbug having commented on the early Overcoming Bias econblog before LW forked from it, bringing with some of his own pre-existing audience. I cannot remember running across anyone talking about Moldbug on LW, at all, besides this post, in the last year or so. Since this page has now risen to the first page of Google results for Mencius Moldbug due to LW's high pagerank, and on at least one occasion sloppy / agenda-promoting journalists such as Klint Finley have found it convenient to pretend to an alternate reality (where Moldbug is popular on LW and Hacker News due to speaking out for angry entitled Silicon Valley elites, or something), a correction in the post seems deserved. See also the Anti-Reactionary FAQ by Scott Alexander (aka Yvain, LW's second-highest-karma user). --EY]
The article is interesting for how badly it misrepresents American history. Intellectual elitist dominance of US policy is a frequently debated topic throughout the history of the United States. Moldbug is right that certain views flowed from academia to public consciousness. But he ignores a lot of other causal factors.
Regarding US race relations, Moldbug ignores that (1) the trend towards pro-civil rights court rulings predates California's Proposition 14 by at least 40 years in cases like Buchanan v. Warley (1917) and Missouri exrel. Gaines (1938) and (2) the prime mover of US political opinion was probably public unwillingness to support the methods of Bull Connor.
Regarding the political tilt of academia, Moldbug ignores the conservative movement's recent success in creating an academic movement that lead to the appointment of conservative judges who have dramatically rolled back US constitutional and statutory interpretation from the more liberal positions of the Warren Court.
Finally, the disparate treatment of unjust tyrants like Castro and Pinochet in academia (1) ignores the different treatment of those regimes by the US government, and (2) partially reflects a feeling of guilt that the US was involved in establishing conservative regimes by taking actions like supporting the coup against Allende or the assassination of Patrice Lumumba and creation of the Mobutu regime. By contrast, there was relatively little US support for the creation of the Castro regime, and thus less culpability for the injustices that followed.
In short, Moldbug's history is incredibly selective - making it impossible to take seriously any of the conclusions he draws from his historical analysis.
That you tout this as a grand example of right wing victory is somewhat surprising, it in my eyes weakens your case considerably for it is a feeble thing compared to the vast cultural shift leftward in the past decades and centuries.
