This... You can't compare Picasso with Van Gogh, can you?
Well I'm thinking more you can't compare Van Gogh with someone's fur fetish doodles on deviantart--both art, but in widely, widely different degrees.
SO you are saying that the word "art" always requires additional specificity? So pop art, commercial art, fine art etc and so forth? That the word art is itself so all encompassing that it has no real meaning?
