I think Japan embraces the universal definition of pedophilia which is different from the definition we are used to, which is to be attracted to someone that hasn't gone through puberty.
Or maybe they think the viewers are mature enough to see the difference between reality & fantasy... idk.
Usually cultures with a ton of perverted media reflects the lack of sex the citizens are having. I did read an article on BBC that said 1/3 of young JP men are uninterested in real relationships & sex. I think too much escapist fantasy could be part of the reason.
Old news is old. Besides, it's so retarded you can't possibly be bothered by it. They don't even look like boobs. Now, Master of Martial Hearts... that was offensive. Talk about mindfucks, the ending of that show was so ridiculously horrifying I don't even. It's like School Days except worse. Shoulda had a nice boat instead.
This is my favourite kind of anime mindfuckery: [link]
