Excerpt:
One in five American Muslims knows of support for extremism in their community, new research has found, despite Muslims being far happier about the state of the US than other groups.
As the 10th anniversary of the September 11 attacks approaches, 21 per cent of respondents told a study they had detected "a great deal" or "a fair deal" of support for extremism in their areas.
While the vast majority said that suicide bombings and other forms of violence against civilians to protect Islam were never justified, 19 per cent of respondents did not agree with this statement.
