Ethics tho. My cousin told me about someone who put a starving puppy on display and called it art. Anything can be art, but is it a free for all?

There's not objective truth, but the answer is yes imo. André Breton, the artist who wrote the surrealist manifesto back in the 1920s, once said "The purest surrealist act is to go out into the street, gun in hand, and shoot randomly into the crowd" - art doesn't have to be good or nice to be art
