What is art?

Art can be anything. Just face it! Art is subjective and no boundaries exist. Period. I am tired of people telling me what it is they think is art. Their individual opinion does not in any way define art. It just reveals what art they like or appreciate. Just because someone does not like or understand something does not mean that it is not art. A Roman Catholic may not understand or like ideas of Buddhism, but that does not take away the FACT that it remains a belief system! C'mon guys, wise up.
