I think that this song is about revolting against the government. Obviously "heads unworthy" means the kings, from which the crown slips when they are being overthrown. "The Children you reject and disregard" means the people that the government tries to reject, similar to the "Long Forgotten Sons." ALso, the second part of this song, the part where they keep referencing "you" is basically saying that even such a revolutionary has a lover, and that once they have either served their time in prison for their actions, or finished the revolution, that they will leave the world of revolutions and power for a quiet life with their loved ones, like Washington.
