Remember how liberals urged Democrats to be more forceful with their message? Which is an even more losing strategy. This is the Hollywood equivalent. Don't hold back. Say what you really think. The results will be catostrophic - for the movie industry.
That's why I'm not as worried about this as the author is. We worried about the success of F9/11, but it didn't change anything. People are smarter than we sometimes give them credit for being. They'll either ignore one of these "WE are the terrorists!" movies, or they'll just go and be entertained and forget about it. I don't think Hollywood has the skill any more to convert people to their ideology.
