I think he's talking about the whole salaryman culture that emerged during the cold war, although it should be note Japan's westernization began a long time ago.
To condense it, i believe he feels something deeply wrong about how Japan's objectification of it's own society has reached such point where even human relationships can be rented, faked at a price (lookup hireable girlfriends/boyfriends etc.)>>33517
sci fi geekiness sure but in general attempting to sexualize lain is very looked down
the attractiveness is one much more akin to camaraderie/self-identification, given how lain does mentions parts where she learns data structures, programming languages etc, something relatable to alot of /g/nerds.>>33487
well, i guess i find it odd that such a site would dislike it, lain is pretty relatable for alot of socially awkward people
