There is an unwritten rule in our society, one that allows parents to raise and guide their children as they see fit, and at an appropriate pace for each and every individual child.
When a child is deemed ready, (or a parent ready to deal with answering the questions), a parent has the availability of their local arts community to introduce a child to the nude form. That is one specific benefit of the established world class art museum, to introduce children to the beauty of the human form.
Aside from your personal taste, or opinion, believe it or not, this snow sculpture would typically be considered as pornography in both the art and philosophy communities. The reason being, that its original intention was to “get attention”, whereas true art is considered as an expression of unique vision. There are infinite dissertations on this subject surrounding the differences between art and porn. Most often, people consider pornography as a sexually explicit act. But that is not the original intended use of the word.
Pornography sets out to entice the physical senses based upon the creators interpretation. Art sets out to entice the spiritual/mental senses based upon the viewers interpretation. There is a difference, one not any better or worse than the other. And in this case, little boys will be walking with little girls while passing this sculpture along the way. There are better methods for introducing our children to the beauty of the naked human form. This sculpture is better left in her back yard for her own enjoyment, rather than being foisted upon all who happen to pass by. Just as an art gallery holds within its confines the essence of beauty that only the human form is capable of expressing. There is a time and place for everything.
