No, Facebook should not censor photos of nude statues. These statues are works of art that were designed to be inspirational and pleasing to the eye. They were not created to arouse sexual feelings. The definition of pornography is material designed to arouse. Since this is not the case with these statues, photos of them should not be censored.
There is no way to know what is going to offend one person or another. Facebook shouldn't have to police other people's free speech on the Internet. Children shouldn't be using Facebook anyways. Perhaps it would be better to raise the minimum age to 18 because that would also prevent cyber bullying with children.
No, Facebook should not censor photos of nude statues, if they are done as fine art. Nude statues are a very real part of our fine arts and culture. To censor them would be to block users from experiencing and sharing arts, culture and history. However, as with all things, they do have to deal with those who use any lack of censorship as an excuse to be dirty, nasty and inappropriate.
Facebook should not censor photos of nude statues. Seriously, this politically correct nonsense is careening out of control. For thousands of years there have been nude statues everywhere. Why, all of a sudden, is it an issue? Are people so mentally fragile that they can't handle it, as opposed to just not looking? Time for people to grow up.
