Interesting again, thanks. I do not think that there is a simple dividing line between graffiti and other art. You ask whether the quality matters with graffiti. If graffiti is just one art form, then quality does not matter any more or less than with different art forms and media. I am unsure whether graffiti is a good idea at Canterbury Cathedral, but perhaps I will get to see it before it is removed, then I can judge for myself.
