Artists act with a superiority complex. Like I was talking to this girl and her mother (both very art oriented) and something reminded me of chibby (Japanese artform, very modern, involves making characters that are cute with awkward proportions) and I brought it up. Then the mother asked, "Did you make it up yourself?. Of course I hadn't, therefore she thought that that was a basis for disqualifying it as an art form, because it wasn't "original". Because y'know, impressionism, modernism and every other art form out there is totally original.
Then they think that manga and anime aren't art forms. It may be true that anime and manga don't seek realism, but they at least are somewhat anatomically correct. They mayn't be drawn to proportion (Orihime from Bleach - No one has boobs that big. Sailor Moon - no one has legs that long. Code Geass - sorry, but those characters are too tall and skinny), but I hardly think that that's grounds for disqualification.
Then there was this very artsy girl, very brilliant. She would not believe that W-RGB-CYM-K was the true color wheel. Even after explaining to her that RYB can't actually make cyan (C) or magenta (M), she refused to believe me. Then she asked what C was! After I told her, she told me that no one ever calls it that.
Art is dancing, cooking, nature itself, Picasso, words, Naruto and fashion! Art is what ever you make it. It just angers me that they disqualify something as an art form because it doesn't mean some insane standards of theirs that seem to me as arbitrary and bias.
