Thanks Roz, it is very interesting to read.

My thoughts on the matter:
I work with young people who speak other languages than English.
Some come from countries where they are told what to think, and since that does not, by and large, happen over here, they lose their points of reference and become easy targets.

I think that, bad as it might sound, a lot of young people want to be told what to believe in... what is right and what is wrong... what is worth fighting for. And radicalisation seems, for some, the best proposal.
