Watching the original BSG opening reminded me of how our fiction follows our society. When the show was created, the great uniting fear of Western society was a 'Red Storm' overwhelming military assault by a faceless, collectivist enemy without individuality or true humanity and aided by foolhardy and self-obsessed traitors (the Communist block, or at least the popular view of it). Whereas, when Ron Moore wrote his own version of the show, the West's overwhelming fear was destruction that came primarily from within in the form of fifth columnists, disguised as fellow citizens, driven by a murderous religious ideology (Islamicist terrorism).
A similar popular awareness is visible in seasons 8-10 of Stargate SG-1 with their new enemy - the religious fundamentalist followers of the Origin religion.
