Here a Muslim former minister discusses radicalisation.
She refers to religious sources but dwells mainly on the internet and never once suggests that BBC or mainstream media plays any part.

"Lady Warsi, who resigned last summer over the government's "morally indefensible" policy on Gaza, said it was becoming more apparent that people were being radicalised in their bedrooms rather than in places of worship."


"Much resource has gone into making sure websites are taken down, but we are fighting an ever-losing battle with extremist groups. One of the things that [Islamic State] has been incredibly successful at has been using the internet and social networking spaces for their own propaganda."
