What's next - book burning?

The Belgian author Hergé (Georges Remi) wrote a book back around 1930 featuring his famous boy-detective Tintin. It reflected 1930 society and views - it could hardly have done otherwise. Many of those views have radically changed over the last 70-odd years, and some of them are now seen as offensive. The Commission for Racial Equality want this book banned. Presumably it's only a matter of time before they also call for the banning of Dickens's "Oliver Twist" and Shakespeare's "Merchant of Venice", both of which portray a stereotype of Jews which I'm sure many of them find offensive. Surely we accept books as mirroring the time in which they were written? What about the many books written during the cold war, which portrayed all those behind the Iron Curtain as duplicitous villains? All rather childish I feel - and with uncomfortable echoes of the "Satanic Verses" business.
