What is your opinion of celebrating "bad art" in a museum?

I don’t consider any art to be “bad art” unless they are suppose to be under a specific rule (like if you are intending to draw realistic portraits but drew a not porportional face, I will consider it as wrong. However if the artist intends to draw something that is semirealistic or in their art style, there will be nothing wrong with it). I don’t consider “bad art” as bad because it was in the intention and purpose of the artist and the things he or she wants to express, so I celebrate all art in museums, including the “bad arts”.
