A naked woman sits on the man's head. As anyone bothering to view the painting can see, Georgione portrayed Venus not fondling her genitals, but modestly covering them. Commentators can make any art appear obscene to those who draw conclusions without seeing the art for themselves. The fact is that, allowing for the rare lapse, experts can. Quite simply, no one is better able to discriminate between strong and weak art than those who have chosen careers in art and studied the discipline for years.
Parallel examples exist in scientific fields.
No one is better able to remove an appendix than a trained surgeon. No one is better able to pilot a rocket than a trained astronaut. No member of Congress would presume to do either. Yet some members of Congress seem eager to back themselves into the curious position of telling the art world what art is. It leads not to 'moral' art but to vapid propaganda.
