People who consider grafitti to be "art" likely are people who don't have children.
haha, Graffiti isnt art?
So using paint to create an image isnt art? What is art? Im glad you can judge others taste and perception about what is art, based solely upon one's status in regards to having children.
Is music made solely on a computer not "art" to you?
Is Free Verse poetry not art because it doesnt rhyme?
Im curious as to why you want to put down a group of artists as creating non art.
Maybe I misread your post.
