Mmmmmmm.........I don't think so. Having been "there" myself, I must disagree. You prefer to believe people operate in a vacuum and there may, in fact, be a couple flaming altruists in the entertainment business, but they are few and far between. Many, many more use the various media to proselytize a left-wing agenda. The contempt for conservatiism is wrtten on everything they produce for public consumption. The snubbing of Mel Gibson and his blockbuster film, "The Passion of The Christ," is proof-positive.
I didn't say that they operate in a vacuum or that they're altruists.
It's a business, so there are few professional altruists. Some of them have their charities that they give to without publicity and some lend their names to charities, but I would assume it happens no more or less than in the "real world."
As for operating in a vacuum, yes, I know they'd be shocked if they realized the impact of their product.
