Just a couple of historical comments:
Triumph of the Will truly is a masterpiece of propaganda, the benchmark against which all other propaganda must be judged and nearly always found wanting in comparison. In cultural context, it puts Roosevelt's New Deal propagando films and Capra's 'Why We Fight' movies in the shade. People viewing it today actually have no idea how effective it was, since they don't understand just how far Germany had fallen in the two post-WW1 crashes; the active, enthusiastic Hitler Youth kids in the film look like cute but brainwashed kids to a modern viewer, who does not understand the fact that they looked well-fed, well-dressed, and healthy was hugely significant to the audience for which the movie was intended.
You can look at Guy Fawkes as fighting for a Catholic theocracy, but at the same time he was fighting against a Protestant theocracy which was no better, just mutually oppressive, and whichever one was the evil oppressor simply depended on whose turn it was to wear the ass-kicking boot. The English legacy of pointless bloodshed, waste, and oppression of the out-of-power religion from Henry VIII onward is the biggest single reason we have First Amendment.
