So the pot is calling the kettle not entirely black next to the black one. They put not quite porn titles next to porn titles.
In a DVD store it would sort of keep children away from perusing such titles. However, these films still show on TV. It also puts into children minds that porn is undesirable, plus these. When some guys figures out things for himself, he will have to all the way back to see a whole lot of titles he missed. I dunno it's confusing.
DVD stores are probably quite common in South Australia, whereas they are almost extinct in other parts of the world.
