AKB48, a manufactured girl group (with over 90 members) that discards members when they get "too old". They are clearly the product of a highly sophisticated culture. If you don't appreciate them, it is only because you are to simple-minded to comprehend.
When it comes to cultural understanding, many Japanese people operate from an unconscious (or conscious) sense that foreigners lack the sophistication to understand their ways. They believe you are the cultural equivalent of a developmentally disabled person. I will not miss this expectation that I lacked the capability to understand and follow Japanese customs.
