Because as we all know, terrorist only speak arabic. Why, there's never been a building blown up by anyone who spoke any other language, right? Arabic == Terrorist.
And people think that Miss Teen South Carolina is somehow uncommonly stupid. But I bet she does great on federally mandated standardized tests. No Child Left Behind has just totally reformed our educational system. Woo-hoo.
I do love this paragraph from the language log post:
It isn't surprising that hearing Arabic might make a passenger wonder, but you'd think that a moment's thought would overcome the impulse to notify the authorities in the absence of additional, more suspicious, behaviour. Indeed, insofar as the systems for detecting weapons and explosives work, there isn't really any reason not to allow people who actually do have terrorist sympathies to fly. As long as you know he has no weapons or explosives, you could let Osama bin Laden on the plane. I'd rather have him as a seatmate than many others - at least he doesn't drink.Yeah.
A clue...speaking arabic no more means you're a terrorist than having a southern accent means that your sibling and your spouse are the same person, or that you and your father can both talk about what it's like to bang your mother. Seriously.
