Not all art is to everyone's tastes. Art often intentionally raises questions about the world and society, challenges ideas and provokes debate. That's part of the point. So it seems wholly wrong that an exhibit should be removed for being "depressing".
There have been plenty of cases of art being censored because of claims that it's offensive, but that's not the case with Andrew Swan's Stinking Rich series. Its only offence has been that a few people thought it was a bit of a downer – on which grounds we would have to remove many masterpieces from the National Gallery and ban the entire Radiohead back catalogue from the radio (see our pick of the best art supplies if you're building your own toolkit).
