Or 'plain as the nose on your face'.
My Pet Jawa distills the obvious into a great analysis:
Terrorists Love the Left (and vice-a-versa).
If Islamofascism and the Religious Right have so much in common, then how come the terrorists never quote Pat Robertson? Instead, they are constanting quoting icons of the Left to support their positions. They even use clips from Fahrenheit 9/11 in this propaganda film.
And when American Taliban Adam Gadahn decides to name drop, it isn't Jerry Falwell that he cites for moral authority. It's George Galloway, Robert Fisk, and Seymour Hersh.
