They're doing the "brainwashing" they accuse others of. Benny Shap's network makes right-wing movies for crying out loud.
They defend this by saying that hollywood is "left" wing ... so they must "counteract" and "balance" things.
I'm reminded of the Chris Wallace and Jon Stewart interview: https://youtu.be/UYbtUztVctI?t=417
Jon Stewart:
Here's the difference between you and I, I'm a comedian first ... my comedy is informed by an ideological background. There's no question about that, but the thing you will never understand and the thing that conservative activists will never understand is that Hollywood, yeah they're liberal, but that's not their primary motivating force. I'm not an activist. I'm a comedian and my comedy is informed by ideology, there's no question about that, but I'm not an ideologue.
