There are many good points in this thread, which led me to this realization: kids are indeed not very interested in national politics, but they are very attuned to the social politics of their peers, which can be pretty cliquish, isolating and devisive.

The propaganda that we are concerned with here deliberately seeks to trigger these childish responses in adults. If you go around telling people that they are entitled to something which these other people are taking from them, you will get some disciples regardless of whether there is any merit to the claim. It is like a mountainside in snow: you will get many small avalanches, but now and again a big one will let loose and sweep everything away.
