>So you called that artist a "vandal". Would you also call Bansky a "vandal"?

He can be both, "vandal" and "artist" aren't mutually exclusive.

>Some people find unapproved grafitti objectionable. How do you feel about that?

I'm not answering for the person you're responding to, but for me, I'd say I feel fine about that. There are people who find nudity in art objectionable; who object to the Mona Lisa; to surreal art; to abstract art; to land art; to a specific artist; to an artistic medium. There's always going to be someone who objects to some form of art, so I'm not sure what you're getting at.

Yes. I like Banksy drawings, really. But Banksy was vandal when Banksy drew his thing on the same wall again and again, while owner quite clearly did not wanted that and kept repainting the wall again again. And to be frank, he was also asshole about it.

Banksy can be both and is both.
