Who decides what art is?

Anyone and everyone can decide what art is because in the world today art can be seen as any thing. There really is no set on what art is andwhat isn't. The only opinion that can be nade about ehat art is, is someone's own perspective about it. The poem, "Adolescence" is seento some as a piece of art that has to be taken apart piece by piece in order to understand the meaning that lies between the lines. The poet, Rita Dove, in this poem invokes her readers to read on about what is really happening within the poem. The problem with this is that those who read this poem and don't uderstand the setting in which it was written in and who wrote it believe to be just nonsense that someone decided to publish. However, when taking about art as whole, art is sometimes easy to understand and grasp and other times the poem or art piece is so extremely abstract that the meaning is lost within the impatience of the reader. So, the person who decides what art is, is the person who can fully support their argument or the conclusion that they have come to with sufficent evidence as to why they think what they do. On the other hand, this presenting of evidence does not even have to be made, seeing that in our society today, the whole freedom of expression concept can really wedge a barrier between what art is and what isn't. The question is not who decides what art is? The question is how do we decide what is based on the principles of what we call freedom of expression? And I know that question sounds extremely redundant, but if there is so much freedom then there can't be a single person that decides what art is.
