Anime encourages pedophilia. "Lolicon" and "lolis" are things often discussed and fantasized about by anime fans. Lolicon is a portmanteau of "Lolita complex," a Japanese expression meaning pedophile attracted to underage girls. The alternate is shotacon, which is the same but with underage boys. Many anime fans call themselves lolicons and masturbate to lolicon anime and manga under the assumption that it isn't child porn. Many non-hentai anime even feature children with erotic undertones. The popular Monogatari franchise is an example; they started with one "loli" character, and her popularity led to them introducing more similar characters and increasing the sexual undertones surrounding those characters. The randoseru, a backpack used by Japanese elementary school children, has been adopted by the anime community as a symbol of lolicon and a sexual symbol. They often argue that it's just anime, and not real, but as studies have shown, pornography leads to the development of new fetishes and subconsciously promotes sexual aggression and promiscuity, so the hentai IS changing them, regardless of if they believe it or not.
Anime encourages unhealthy and unhygienic living. One need only to go to an anime convention to see it. Most of the people present are overweight, smell as if they haven't showered in a long time, or both. Most anime fans will binge watch a particular series if it has already ended, and most series are at or near any multiple of 13 for their episode count, which means hours spent sitting at a screen, staring, not doing any exercise of any sort. Visual novels (a child of anime) help encourage these people to let themselves go, making them believe they can succeed and get a romantic partner regardless of what they are.
Anime encourages social ineptitude. Many anime fans, instead of pursuing real relationships, are encouraged by anime to have a "waifu" or "husbando," an anime character they have romantic feelings for, to substitute a real person. As mentioned prior, anime fans often hide away in their rooms watching anime and not going out into public, preventing social interaction. Visual novels also give them what they feel is a substitute for interaction with people. Anime itself glorifies social ineptitude, with many anime in the "ecchi" and "harem" genres featuring protagonists who are socially inept but still manage to garner the attention of multiple attractive females, creating inaccurate views of reality.
Anime encourages sexual perversion. Anime fans often develop strange sexual perversions and fetishes thanks to anime and related material. Fans of the vertical shooter game "Touhou Project" have shown a fetish for armpits thanks to the protagonist's design. Thanks to anime-type material such as the visual novel Monster Girl Quest and the Monster Girl Encyclopedia, "teraphilia," or a fetish for monsters, has come into existence. Hentai (pornographic) anime and manga often features rape, sexual violence, and strange fetishes like tentacles, and borderline bestiality with thinks like "catgirls" and monster girls.
