They shouldn't, but they will. Because that is what Hollyweird is today. It is a gigantic testing and propaganda outlet for unchecked liberalism. You can scarcely find any tv show or movie that doesn't express and promote liberal/leftist values.
The people who make movies are mostly liberals who hire liberal actors for their mostly lousy p.c. flicks.
During the last Iraq war there was a ton of anti-Iraq war movies made, and no pro war movies. Every one of those movies flopped proving the claim that Hollyweird only cares about making money to be a lie.
A movie about the Marines taking Fallujah would have made multi millions. The big shot producers and actors in Hollyweird simply didn't want to make one.
Make no mistake, even in the old days most of what Hollyweird churned out was garbage. But today the garbage to good movie ratio is a lot worse.
So don't expect Hollyweird actors and big shots to quit preaching to us any time soon. It is what they are....a bunch of hypocritical liberal losers who can't resist telling everybody else how to live their lives.
