Why does the American society condemn public nudity when other countries do not!

Hi everyone and happy Saturday night. My husband and I have been nudists all of our adult life and we always thought that by the time we were 60 (which we are now) the United States would have accepted public nudity as other countries have. With the onset of the internet, we are even more curious why public nudity is not just seen as an activity the people have the freedom to engage in and it being no big deal because it is commonplace. We raised out son and daughter in the nudist lifestyle and they are well adjusted adults now and still participate when they can.
We would love to discuss the pros and cons with anyone who is interested. Obviously, we are very convertible with the subject so please feel free to aske anything you would like.
