I feel that art is very expressive in many ways. You can paint, draw, or sculpt what you feel or experience. I also agree with J. Whalen in that we are fortunate to have the privledge of art. It's true that some countries do not allow any form of expression or art.
Art can be very meaningful.
It can be a weapon of power. I think it is wonderful to have a form of expression. You express your fears, dreams, etc.
