This is from the same Guardian article as my previous post, but I thought it deserved its own post.
Via the Guardian:
The MPs do conclude that there may be growing support for nonviolent extremism within the Muslim community, fed by feelings of alienation and a sense of grievance, and this is a challenge for society and the police.
They recommend that tackling Islamophobia and demonstrating that the British state is not antithetical to Islam should constitute a big part of the official Prevent strategy designed to counter the ideology that feeds violent radicalisation.
The MPs talked to the radical preacher Abu Hamza in the maximum security unit at Belmarsh prison in London, who told them the main drivers of radicalisation were grievances, especially concerning Palestine and Afghanistan, a sense that the prophet was being mocked, guilt and capability.
He said unemployment was not a source of grievance.
