As far as I can tell the message of the movie is "consumerism is bad because it's emasculating and feminizing, real liberation can be found in ruthless hierarchies of masculine violence"
The only person I know who likes it IRL also has a tendency to complain about the "pussification of modern men"
That's a good summary of one character's belief system, but the thesis of the movie is "Wow that guy is fucking crazy."
