All the items you cite do align more closely with the right side of the American political spectrum, not the left.
Yet the messaging that comes out of Hollywood is overwhelmingly leftist. You can't watch an awards show without seeing several 'spontaneous' outbursts against Republican politicians, in favor of left-leaning policies, etc.
Why is this? Why do these people look like typical Republicans but speak like rabid Democrats?
My theory (as explained above, and bolstered by testimony from Allen, Woods, etc.) is that money, job prospects, and awards are used as incentives to publicly tow the party line (without regard to the person's actual opinions.) We know these tactics were used to great avail in the Weinstein playbook. It's why none of his victims came forward-- they were mostly starlets that wanted to work.
Of course I'm not certain. Does anybody have a better theory for why those people seem to 'live' right-side, but 'shout out' left-side?
