Do you actually read what others post, or more to the point do you comprehend it? In order to be brainwashed by a movie, you need to believe it is a true account, or at least in the message that it is preported to contain. I see the Avatar movie as an entertainment, I do not go away believing any message, I don't take anything from the movie. It is what it is , to me, a piece of fantasy entertainment. Propaganda only works if you get sucked in by it, which you obviously have been.
If it helps you to comprehend, read my post as many times as you need to.
