tagging and graffiti is art.
Discussion
Tagging is not art. It's the product of egotistical scum who celebrate themselves by putting their name everywhere they can. They destroy other people's property for their own self-aggrandizement. And when the property owners make the expense of painting over their tags, they're back the next day to put their name on the brand new blank spot. Because one-upping the people who own and maintain property is part of the excitement for them.
GM. What is art?
Art doesn't involve destroying other people's property over and over again. There's a world of difference between taggers and graffiti artists. One produces art, and the other is a parasitic scumbag with no regard for anyone but themselves.
Nobody produces art. Things are created, or destroyed, by people using tools. The viewer of the thing gets to decide if it is art, or not.
Also, most people that have been generally accepted as good artists typically have no regard for anyone but themselves.
