Anime? art or not?

So I see this question a lot and thought I would like to rant about it in my blog. "Is anime really art?" now for those not familiar anime (or manga) it is japanese style cartoons, often characterized with big eyes and even bigger expressions and some great humor. So in short it is a cartoon form but in a completely different style to cartoons of the west. Quite often i run across the controversy where people say anime isn't art...which puzzles me because last time I checked it is a drawing form and drawing is an art form so therefore wouldn't it be art? Seriously if someone can take a Urinal and turn it on its side then put it in a museum with a signature on it and call it art then this cartoon art form IS art. Art in my opinion has many definitions and should not be confined to just one meaning.
