No actually I'm agreeing with you. James Woods is openly Conservative, and it ruined his career. He said so himself. Lol sorry I should've been more clear.
I believe in hiring the best people for the job. Intolerance in Hollywood literally blacklists people for being politically conservative, meaning we might not be getting the best actor/director for the job.
That's their prerogative.
Incidentally though, Clint Eastwood and Mel Gibson are two examples where your assertion doesn't seem to apply. They've never seemed to struggle.
Eastwood was established before Hollywood got radicalized. Gibson was established in Australia.
They have to get them before they become a star and that's what they do.
