First, President Obama took the occasion of a national address to inform the country that “ISIL is not Islamic.” British Prime Minister David Cameron seemed to echo that surprise comment today in a statement on the beheading of David Haines, saying that ISIL “are not Muslims. They are monsters.”

A coalition of U.K. Muslim leaders seems to have taken a shine to the idea that the Islamic State isn’t Islamic, demanding that ISIS be called “the Un-Islamic State.”

The Independent reports:

A group of prominent Muslims has written to David Cameron to ask that he uses a different name for the group, and to lead a national debate on what it should be called.

“We propose that ‘Un-Islamic State’ (UIS) could be an accurate and fair alternative name to describe this group and its agenda – and we will begin to call it that,” the letter says.

Signatories to the letter include Sughra Ahmed, the president of the Islamic Society of Britain. Members of New Horizons in British Islam, the Association of British Muslims and the Association of Muslim Lawyers also signed the letter.

Using the group’s preferred name could help it radicalise yet more Britons, the signatories wrote.

“We need to work together and make sure that these fanatics don’t get the propaganda that they feed off,” the letter says.
