It's true that various sites are considered the stories of particular groups ( men V. women, these people V those people) .. but aside from that specific consideration they haven't been censored in the sense of ( painted over | black barred | altered ) or hidden (cave | over hang moved or draped with a false rock).
The major thrust of this sub thread has been about line of original purity more than an obligation for [some group] to openly share to all regardless so forgive me if I still consider these a good example of unaltered works painted on and carved into stone.
