You have much to learn about otaku culture, young Padawan, before a proper explanation to why you got that impression can be given, and I think that's a rabbit hole you are better off not going down. It's not for the uninitiated.
Looks like you haven't been to the dark part of the Internet yet. Good luck and Godspeed.
Don't mistake me for naive or surprised; I'm simply pointing out something that comes across as screwy (excuse the pun, I didn't notice it until I reread the sentence). Sure, there's far weirder, [censored] up, and blatant out there (just look through the TVTropes forums*), but that doesn't make anything better than it would otherwise be.
*Doing so may have decreased my tolerance when it comes to these things...
EDIT: BTW, I'm not anit-anime; I have enjoyed a few, including Samurai Champloo and Ghost In The Shell (watched at least the first two movies and SAC).
