Well depending who you ask the answer can vary. As a dancer myself for 43 years I stay true to my belief that dance is an art. Are dancers athletes? Yes! Absolutely! Some of the strongest in the world. However they are not playing a sport but instead performing an art form. Dance is subjective.
There is codified movement but all styles and forms of dance are open to interpretation. The beauty of dance as with all art forms is in the uniqueness and inspiration that it creates for the viewers/audience. It will invoke something within you that maybe was not there prior to experiencing it. No matter what side of the fence you are on remember that everyone can and in fact should dance. There are so many more benefits than just the simple beauty and we could always use some inspiration that this art form certainly projects.
