Um, isn't today's society based on worship of idols, no matter what, or who it is? Sure, it doesn't mean going by every word that comes out of your chosen idol's mouth, but it does mean that you have reason to buy posters, Cds, movies, or whatever else you want. Which also drives the economy, or so it seems.
Maybe most don't worship Batman, Superman, or any fictional famous character to the extent that the Bible mentions, but them saying this now, is a little late. They should've tried that crap around the 40s to the 60s, when it was only a growing market, not a full fledged industry.
