The terrorists aren't oppressed by poverty. Bin Laden was a millionaire. They aren't beaten down by lack of work, they're quitting jobs to join Jihad. They aren't directionless, they know exactly where they're going. They aren't misguided souls, they're people who have exchanged their souls for a sanction for torture and murder. They're doing this because they like it. And whatever else you might say about them, they're perfectly honest on that point.
Go away, Marie, for God's sake just swap your classroom bromides for a clue in the real world, because sooner or later the real world will come calling and it won't be for a nice dorm-room conversation on "root causes."
Good post.
