How is having an opinion on something as wildly subjective as art make anyone here a philistine?
I could agree if people here were denouncing the cultural value of all art be it (subjectively) good or bad but no one is, it's merely differing perspective on what art actually is. My personal opinion is that art is anything that means something to the artist, that has a point to it, even if just for that one person, art is not limited purely to the technical skill of the artist but more to the passion, devotion and vision of a human being.
However, I think that if you're going to have this kind of argument over something so very, very subjective as art, you're going to have another politics or religion thread on your hands.
