Douglas Murray wrote in The Sepctator Magazine in 2011 here:
"Self-censorship is the most invidious and successful type of censorship – not just because it is self-reinforcing but because once it is people invent reasons to cover for themselves. So the worst thing that any British journal can imagine doing today is to run a cartoon of Muhammad. Not because – as they all say in public – it is insensitive, or provocative or offensive. These are all names and things that journalists rejoice in getting called. It is simply and solely (as they sometimes admit in private) because they know that they will be at some degree of risk if they do."
Nick Cohen wrote that censorship is at its most effective when no one admits it exists here:
"Censorship is at its most effective when no one admits it exists."
"Many liberals, out of a fear of appearing racist, and with shared sympathy for many of the political causes that also motivate those with a fundamentalist agenda turn a blind eye to such intolerance."Wilbur Smith is known for saying: "Quite frankly, I think political correctness is the worst form of censorship." Al WeiWei has said also: "Censorship is saying: 'Im the who says the last sentence. Whatever you say, the conclusion is mine."
