Well I think when you tap into folks unconscious bias, it likely goes totally unnoticed. In fact I would probably say some of it was likely unconscious to the filmmakers as well. When you take your own perspective for granted I think it's also pretty easy take for granted the inherent nobility of one trope vs the "obvious" evil of another. I do think that most folks who might recognize it would be very much in favor anyway, and not see it even remotely as a problem, but rather, as a cultural victory of some kind.
Then there are people like me who find fault in everything because they see a world seething and writhing with obscene injustice. It colors everything I look at. I don't think it's the same as stereotyping, in fact, it isn't at all because it's based in empiricism, empathy, and ethics...but I don't necessarily think its completely healthy and totally "right" either.
The reality of the movie is probably somewhere between my own view, the "blindness" of others', and those out there who see it as a morally correct and necessary propagandist allegory. However, the Palestinians who write and ridicule the movie probably see just about everything I do as well.
