And while your numbers may be accurate, they're also very high-level. Only broken down into very general categories like "Online games", "figures", "light novels" and "anime DVDs". Am I supposed to believe that every single anime DVD sold at Akihabara was some kind of weird moe fetish? Though I'm guessing your reports probably account for every single DVD sold at Akihabara, without discriminating for only "moe" DVDs. At least not on any of the reports you cited.
Your mistake was thinking that I was making a counter-claim. I never did. I was merely questioning the lapse in logic that leads people like you to believe that the sales of Otaku-related merchandise somehow means that Otaku are the only ones buying such things, and that therefore those things can only possibly appeal to Otaku.
