LOVE this series. Incredible production and art value in addition to political angles. Also incidentally the highest budget series in EU history, so they say.
Although she has her problems, Cassandra Fairbanks on twatter has done a lot of research on these shooters, their online groups, and the importance of such symbolism to them. People tend to blow her off b/c she's not talking gunctrl but she's lurked a lot among them and always notices their icons/outfits/symbols.
