The blurb for the show from the iplayer page:

Investigation which uncovers disturbing evidence that some Muslim children are being exposed to extremist preachers and fundamentalist Islamic groups. We also expose the part-time schools where hate is on the curriculum. The programme asks why school inspectors have missed the warning signs and examines the impact this could have on young Muslims' ability to integrate into mainstream British life.

To me it seems like scaremongering mostly...
