Lyric discussion by Romsca 

Cover art for Open Fire lyrics by Wednesday Night Heroes

This song is a "battlecry" in response to the fear the mainstream has of individualism (but being unified as humans, hence the 3rd stanza) and how those that don't conform tend to be marginalized, the firing squad situation being a metaphor for the opppression of the masses. It's an angry retort in response to how society percieves people that dont fit into the mould, and its a call to arms to rebel against the popular authority.
