This quote from the linked article troubles me,
“It’s not the letter that is going viral. It’s a selective reading of parts of the letter that’s going viral,” Charlie Winter, a specialist in Islamist militant affairs … (said). “And I don’t know whether it’s because people aren’t actually reading it or, when they’re reading it, they’re reading the bits that they want to see.”
What does he want people to do? "
The letter advocates for violence and theocracy, so every part of it is bad" is what I seem to hear him saying. We should not look at why people are angry at us, only see that they are angry at us.
Selective reading is a valuable way to get information. We do not really need to read the parts about how it is good to kill Americans or that the world should embrace Islam, because those ideas are not meaningful to us, and we will never support those things. But the parts where he explains al Qaeda's origins, the underlying causes for their terrorism, is worth looking at. It is much easier to contend with an enemy if you take some time to understand them and not just blithely brand them as evil.
