Graffiti is known for it vandalism. Yeah it's an art form, but why do you think they call it graffiti, because of the way it is used. graffiti is like an adjective. Others see it as vandalism, others take time to actually look at their work and respect it. Graffiti is art, theres no arguing that. But its mainly tagging and all of that stuff, weird looking words, something where the artists puts it down on something whether it be a wall or paper, they hope for someone who respects graffiti and wont judge them. Graffiti is mostly looked down upon because where it usually takes place, the walls. Theres my elaboration.
