I don't know that these people understand the term "atheism" or have unwittingly hijacked it to mean "against extremist religion" for there is not a lot, beyond personal and untrained anecdotal observation, to chew on in any academic sense. If you've ever heard Joseph Campbell speak on the subject, you'd realize how bush league and irresponsible this is. Atheism is now it's own market and has put these guys on the road to promote the film. Untold semiological crimes are being committed in the name of commerce and personal financial agendas, the first being the blurring of the term "atheism". These kinds of irresponsible broad releases can really backfire if the players don't have their terms and definitions in order and decline to include anyone who may have studied the subject seriously. Lots of books are being sold and our cultural philosophy is, once again, being determined by editors who are responsible for selling books and movies. Only this time, we are not modifying the definition of family, planting a product brand into our cultural consciousness or associating a core value with a car. We are talking about using a core belief (or unbelief) system potentially as a vehicle for something totally unrelated that will have many opportunities for adulteration and being re-fit to market along the way (like any brand.) None of these guys are saying much beyond a fairly surface polemic against an obviously delusional minority (I think they may be pumping the stats for their own ends as well.) Very hard to believe that half of the population does not understand or give any credence to the theory of evolution despite it's universal acceptance by all the major religions and it's instruction in faith based schools for more than half a century.
I would take their own advice and not believe everything you hear.
