I don't especially want to defend my criticism, but my basic point was that quoting reams of material on tribal warfare does nothing at all towards addressing the LW 'tribalism' view of personal identity & group solidarity as fundamentally motivated cognition and is a giant non sequitur, and his attempt to contextualize the Byzantine isn't much better because pointing out that factions latched onto the mobs is like saying there is no such thing as xenophobia or nationalism because in China the xenophobic nationalist mobs protesting Korea or Japan are manipulated by the government and shut down when necessary - if people really are easily manipulated and propagandized as part of group conflict, you would expect various factions to exploit this.
More concisely, the article presents a long and elaborate rebuttal to the name "tribalism" without actually discussing the concept of tribalism at all. It also points out the fancy in Eliezer's fanciful example at great length.
Various people (including Konkvistador who has been talking about it the most) have launched their blog More Right
"A group blog, More Right is a place to discuss the many things that are touched by politics that we prefer wouldn’t be, as well as right wing ideas in general. It grew out of the correspondences among like minded people in late 2012, who first began their journey studying the findings of modern cognitive science on the failings of human reasoning and ended it reading serious 19th century gentlemen denouncing democracy. Surveying modernity, we found cracks in its façade. Findings and seemingly correct ideas, carefully bolted down and hidden, met with disapproving stares and inarticulate denunciation when unearthed. This only whetted our appetites. Proceeding from the surface to the foundations, we found them lacking. This is reflected in the spirit of the site."
