It just the matter of how you define "art" by yourself. Just like we all are different, the definition of "art" is different for all of us. Some people think Picasso's art is an art, but others would say it's a bull shit. Some people would think "porn" is art, but others say "no, its just a porn". Same to Hentai, Otaku, Anime, and so forth.
