Do remember that CERTAIN types of "Chuunibyou" are considered PERFECTLY mature and acceptable by westernized society.
For example, it is considered a sign of maturity and intelligence to worship the ground walked on by some British dude called joe-pee-pee-maltin who scribbled some crap called play-of-chairs about incestuous medieval assholes who throw innocent children out windows while whoring out their own-sisters' virginity for the eggs of fire vomiting lizards with wings.
Whereas, (actual personal experience) if you DARE to openly love
K-ON! and
A Certain Scientific Railgun, (Anime/Manga of friendship, courage, hopes and dreams) over play-of-chairs in the Australian Fanboy Community, you are an immature, deluded, evil white hating Asian-supremacist pedophile.
