Agreed, Freya, about the message. The example should should say ‘terrorism’ though.

The author did not call the Afghan people, the terrorists – here the author has mentioned the action of British military against terrorism in Afghanistan. There is nothing wrong with the above example.

I found this website very helpful. But sad to read the example of this idiom. There could be other example. Calling afghan people terrorist is not a good thing specially in academic and educational platform. I request admin to take down such examples which can hurt a community and add alternate examples. thanks
