The way they're pushing otaku culture onto the people of another world kinda leaves a bad taste in my mouth. Those rebels have every right to be pissed off becuase it really -is- trash that they're teaching their people when you get down to it. They don't want to teach the different races to understand each other and get along but are okay with teaching them all about moe and boys love. Rather than teach them how to read and wright they build a school in the new world to teach them about Zettai Ryouiki. The show could probably do to let a bit more lose and take itself a tad bit less seriously with that stuff in mind or at least leave out some of the drama and conflict till latter in the show. This isn't a premise that should be taken seriously at all, yet stuff like with that hostage situation only serve to highlight how fucked up it would be if we really did discover a new unspoiled world like that and teach them almost exclusively about a generally looked down upon subculture.
It's kind of depressing how this show reminds me of the piss poor track record our modern world has with newly discovered previously uncontacted civilizations. such as in like in south America, Peru, or Brazil. They have a tendency to develop problems with alcoholism, rampant disease, slave labor, sexual exploitation and so on. but I suppose in light of that, teaching them about 'no pan' isn't so bad in comparison.
