Oel ngati kameie ma Ja'k, As for your question, imo, its because no matter what the movie is about, if there are people who like it and enjoy it and want to take the point the movie has to heart, even if it has an important message, it comes down to the fact that there are always tragic souls that like to cause uncomfort for others, they enjoy the thought of ruining others fun, or making light of things that the members of the community see as important. I also can't understand it, but I guess its just a human illness to like to ruin someone elses parade. That being said, I will never let them ruin my experience, and stop me from talking to my Avatar friends and I will try to do my best to remember the message from the movie while at the same time enjoy the ride of the Avatar franchise. I will enjoy walking past the decomissioned Amp suit on Pandora in two weeks, to personally see the ruins of the greedy and evil RDA for myself, Hell yea!!
