Prejudice against Muslims has "passed the dinner-table test" and become socially acceptable in the UK, a senior Conservative is to say. Baroness Warsi, co-chairman of the Tory Party, will warn against dividing Muslims into moderates and extremists. The baroness, the first Muslim woman to serve in the cabinet, will say such labels fuel misunderstanding. She will use a speech at Leicester University to accuse the media of superficial discussion of Islam. Baroness Warsi will say anti-Muslim prejudice is now seen by many Britons as normal and uncontroversial, and she will use her position to fight an "ongoing battle against bigotry".
