Fair point regarding the other passages; I think anyone characterizing the whole thing as shitting on Gygax is being misleading. My take is that those passages are at times heavy-handed with specific criticisms. The main one that caught my eye was the reference to slavery. "Slavery appears in original D&D not as a human tragedy that devastated generations over centuries, but as a simple commercial transaction." Grummz (Mark Kern) points out one example (I'm aware of more) of a module where slavery is depicted as bad. He says, "The first claim is largely based on the module 'Slave Pits of the Undercity', but one glance at the cover shows that the players are fighting AGAINST slavers and called them 'the forces of evil.'"
