Banksy works to be painted over

I think graffiti is art and also vandalism.Graffiti is art because of the use of the colours, the delivered messages from some extraordinary artists, and the representation of beautiful paintings. Sometimes viewing graffiti art on the walls, in subways and on buildings is much like viewing contemporary art in a gallery and a graffiti piece can totally decorate an appropirate location.But graffiti is also vandalism in some points of view. I wouldn't like to wake up one morning and find the walls of my new house covered in a graffiti piece. It wouldn't fit with the decoration I choose for my home.
