Why do nazis love flaming torches so much? They’re a very dangerous and impractical thing to bring to a demonstration. Do they use they because they know the cops will never stop them and so don’t need to worry about that sort of thing?
Cuz it looked cool in Triumph of the Will and the alternative ways of looking cool on a parade take a shit ton of training and discipline and coordination that they can’t pull off.
In addition to other comments, they probably have some feeling that it intimidates potential protestors to be carrying a flaming stick.
Maybe they are also going for causing a variation of the “suspension bridge effect” in their followers to be carrying and surrounded by dangerous objects.
