I think there is a divide here which cannot be bridged. You see, I see art which you might call "political or social" as significant and as valid as traditional living room art.
Art that makes one think, question, debate. Art is not here just to make beautiful unquestioning objects: artists have always, from the beginning of time, also made work that has strong political and religious significance.
For example, the portrayal of the horrors of war: it's necessary "lest we forget". Images and statues show what words alone cannot.
Fine, if you want lovely landscapes: as an artist, I've done a lot of that myself: one can cross boundaries as I have also done in the representation of the female body not as traditional painting has done for hundreds of years and political images, ditto. Art encompasses them all.
In the Banksy cathedral picture, not knowing what the boy is praying for is part of what we have to work out ourselves.
Notice he has a paint pot in front of him. He may have done the graffiti, but it is very lovely graffiti, in fact not dissimilar to abstract paintings
which fetch hundreds of thousands of pounds if you are a famous abstract painter
Is he praying for a better life, and this is his way of expressing himself?
That, we have to work out for ourselves.
This would under normal circumstances be headline news
