Who here believes every single word in the Daily Mail?
Who here is proud to say they don't trust a word that's printed in it? Oooh, that was quite a lot of people, I think. Bit unfair, acksherly; the Daily Mail reliably gets the date right!
I can hear a lot of other people protesting to say they treat particular papers, such as the darling DM with pinches of salt, according to detected biases, and depending on the story, rather than blanket believing/disbelieving the paper. Yes, that's a very adult, nuanced point of view.
Wondering where I'm going with this? Well, I agree that ISIS's evil has been covered in mainstream media. The girls must have been aware. However, I don't agree that these teenage girls necessarily trusted the reports in mainstream media. It is possible they really did believe, lock, stock and barrel in the version of events and justifications they were getting from ISIS agents over the internet. The idea that you and you (and a couple of friends) alone are the only one(s) who knows 'the truth' about 'what's really happening' is an attractive one; it's particularly attractive at 15. Heaven knows, there has been an anti-Muslim slant in the press for years, and I can see how a skilled groomer could harp on that to discredit the accuracy of reports on ISIS.
Sometimes, it's just a matter of terms. What's the actual difference between a freedom-fighter, a guerilla or a terrorist? I'd call ISIS barbaric pillagers, but "freedom fighter" sounds much more positive, and it's such an easy substitute for terrorist.
