Well, I only knew a single Palestinian personally so far and she surely didn't identify herself with Bin Laden or his views. Through her I came to know that there are probably only two kinds of Palestinians in the world: the radical Islamist and the secular left-wing nationalist type. (Doesn't mean she was a Fatah supporter though. She thought of the Arafat/Abbas clique as corrupt douchebags. There's certainly a branch of Palestinians who hate Israel, Fatah, and Hamas alike.
Palestinians are also complicated.)
