Art must never be censored.
Not ever.
It depends on the local context. Michael Angelo 's Statue of David replica (in Kensington) was censored with a big fig leaf apparently on instructions from Queen Victoria.
Granted that was almost a century ago. But I would say we in South Africa (especially black people ) are at least 50 years behind England with regards to tolerance for nudity. Give us time and we will eventually get there. Don't try and force the issue.
