Hollywood is really just trying to stay relevant.
Hollywood has controlled the entertainment industry for nearly an entire century now.
Hollywood has almost fully controlled our entertainment and communications industry for decades through various mediums such as movies, TV, radio, fashion, and music, but there is one medium that has come along recently that they have never really been able to control and that is the internet.
The internet which was not born out of Hollywood and has become a worldwide phenomenon is quickly replacing Hollywood born things like television, radio, movies and music in the states.
Used to a person wanting to be a star would travel to California hoping to be discovered and make it big. The Hollywood big wigs had full control over who those people were to become stars. They were able to find the few they wanted and cast out the ones they didn't. They used people for a time and just spit them out when they didn't want them anymore. Lets face facts, Hollywood has not been ran by very humane people.
The internet on the other hand is the new kid on the block, the medium that for the last few decades has been replacing Hollywood mediums and has been able to bring everyday people into the spotlight and allow worldwide communication by every day people like never before.
As Hollywood has been becoming irrelevant the desperate Hollywood royals have seen the writing on the wall. They have had to battle like never before and while Hollywood has always been political to a degree, and it has mainly leaned left because of the Democrat party's propensity to fund the arts more than the Republicans, but Hollywood has never been as blatantly outspoken as the last couple of decades. Sure you could argue they had some relevant points with George W Bush as even a lot of Republicans turned against Bush because of the failed and unlawful Iraq War. President Trump himself was against the war. Maybe not as much as the beginning as he likes to clam, but it isn't like Hillary Clinton didn't actually VOTE for the war as US Senator, but I will digress as that is a subject for another argument. Hollywood is now resorting to politics to try to stay in the fray. It is not like they really believe the crap they spew. These are the last people who should be preaching about causes related to humanity, and they get so much wrong (especially lately).
Many of the most dementedly outspoken stars as of late have been Hollywood's has-beens. People like Ashley Judd, Madonna, Rosie O'Donnell, Shia Labeouf, Miley Cyrus, etc. Hollywood is built around publicity and is something these stars are used to and strive for. If they are not getting it through movies or music or TV anymore they try other things, in this case politics. The thing is that unlike people like Ronald Reagan, they aren't dropping out of Hollywood to run for any office. California already has a governor and they wouldn't be elected to anything most anywhere else as many of these stars are total idiots about politics. There are also those entertainers who haven't made it big so far who are also looking for their 15 minutes, like David Harbour and Michael Shannon (although Shannon should be arrested in my opinion, he threatened people).
Maybe these people should be pitied more than reviled. I don't know, I am really just glad they are on their way out. We have had enough of this elitism among people we never elected to any office. They can continue talking down to us as they go right out the door. Bye bye!
