How normal is being redefined?

Jeremy Keith shares fantastic words about the normalcy of The Sun's Page 3 feature of a topless model. There is a campaign to eliminate Page 3 but some are backlashing against it because of the historical precedence of Page 3 feature. It has become a normal attribute associated with the newspaper. But when is normal normal and what does mean in the face of changing cultural mores?

So what do we do? Do we simply accept it? Do we shrug our shoulders and say “Oh, well”? Do we treat it like some kind of unchangeable immovable force of nature; that once you have a large online community, bad behaviour should be accepted as the default mode of discourse?
