gerg said:The concept of "art" can mean something significant without relying on a particular quality which is present in a piece.
That's not what I'm saying. What I'm saying is that if people are going to expand the definition of 'art' to mean, "Anything I think of as art, is art" - if it's going to be used in such a flexible, all-encompassing manner - then (a) there is no reason to be upset when someone says something isn't art, and (b) it makes the term meaningless because it lacks any true definition.
A word without definition, or one so in flux as to include anything ever, is worthless.
