In an interview the Prime Minister – said by a Downing Street source to be "livid" about the attacks on his speech – stood by his philosophy. "You have to confront the extremism itself," he said."You have to say to the people in Birmingham Central Mosque, or wherever, who are saying 9/11 is a Jewish conspiracy, that that is not an acceptable attitude to have.It would appear that entertaining strange theories is no longer permitted in Britain. While I shed few tears for the troofers, Holocaust deniers, creationists, climate change 'sceptics,' Dr Kelly doubters and the like, it suggests a worrying precedent. What else might be judged 'not an acceptable attitude to have.'
"We don't tolerate racism in our society carried out by white people; we shouldn't tolerate extremism carried out by other people. (1)
This prohibition on unBritish opinions also gibes with the right to free speech - which Cameron had endorsed as a fundamentally British value. It would appear you are free to say what you like, as long as it is the approved version.
One assumes he will also be taking measures against the endless stream of anti-semetic ravinga produced by the far right and the holocaust denial industry. Or is the 'British values' stick one specifically reserved for whacking Muslims with?
