As to the point of the article, I don't think that Hollywood will appreciably change until the people change, either inside or by different people. Currently, the Hollywood elite are more committed to drugs, homosexuality and perversion than to anything else, including making money.
Steven Spielberg and Jeff Katzenberg vowed to get Mel Gibson blackballed in Hollywood for making "The Passion of the Christ." They only backed off when their quotes were made public, generating backlash.
Speilberg was asked about the Gibson film when it came out and declined to comment. Where do you get this information? Films about homosexuality and perversion represent a rather small percentage of Hollywood product.
