Hollywood culture and the product that Hollywood produces is overwhelmingly left, with a few lonely patches of Conservatives who keep their heads down rather than expose themselves to the politics of destruction. If you disagree with leftist newspeak then you are evil and deserve to lose your livelihood.
Hollywood might be left, but the art world actually puts Hollywood to shame in its unwavering and reflexive leftism. Check out the major art websites and you will discover an endless parade of anti-Trump art.
Art: I use the term advisedly. Most of the pieces do not rise above the level of the crudest propaganda. In the art capitals of the world, artists compete with each other in hating Trump and those who voted for him.
