“…either way black with bandannas is” an alienating and easily identifiable costume. Do the ordinary people in the communities you are trying to organize (who are not in your subculture) wear the same “uniform” as you? It is also hypocritical because the clothes were acquired from multinational corporations and many of these people have anti-capitalist philosophies, hence putting fashion/lifestyle before politics. Do the political philosophers that you’re following wear black?  Do similar movements in other countries (Spanish civil war, zapatistas, Argentinian workers, etc) wear black? Black bloc is fine and cool and useful as a tactic at an action but “politics turn into subculture when tactics become lifestyle and lifestyle becomes politics.
