One proof of Hollywood bias against conservatives is Mel Gibson using his own money to produce the Passsion of Christ, a block buster hit by any standard. One thing Hollwood is good at is churning movies that are derivied from recent hits. How many movies were produced that were riding on the coatails of the Passion?
An employer in Hollywood’s apologized to me for being unable to hie me, saying the union would not allow him to hire me. The union in California contacted the union/s in my Midwestern community to determine that my family was generally known to be Republicans. Because The union would not permit a Republican to be hired if and when they could block the hiring.
There is a well known habit of many Hollywood executives and producers tsaying they will not hire Republicans or conservative Democrats.
The universities also have a habit of using conservative and Republican students to meet their quota of students they delliberately fail to make it appear they are culling out underpreforming students. Conservative teachers are not welcome in the teaching profession, and efforts are made to exclude and drive out any teachers who manage to get into the profession while being a Republican or a conservative Democrat.
In other words, Hollywood and Liberals are prejudiced bigots.
