Is Hollywood predominantly Liberal because they have lost the ability to discern reality from the fantasy worlds they inhabit, far removed from logic and reason?

No. The reality is we only know the political views of a few celebrities and media personalities. To assume they are all Liberal is as stupid as assuming Bush was a Liberal because he signed legislation Liberals wrote. The fact is that the television networks are Liberal (except FOX) and they focus on celebrities who share their ideological views.

But here's the thing... all the networks are owned by Conservative corporations and they're losing millions of dollars by staying leftwing as that gives FOX exclusive viewership of rightwing and right leaning Moderates so on any given day FOX has more viewers than all the other networks combined... because all the other networks split the other half of American viewers between them which is a losing proposition.

So why do rightwing corporations own leftwing news networks losing hundreds of millions of dollars?

Think about it... they choose leftwing news personalities to make leftwing viewers stupid. It's just that simple because these rightwing corporations know that controlling information controls those on the receiving end and since the 1970's when the news media outlets shifted to the left, the political left has become so blind, ignorant and downright oblivious to reality at times that many of them are filled with hate for the political right because they can't understand what's wrong within their own ideological views that they fail at everything. Maybe they still view that they are on a moral high ground because of the ideals behind the ideology, they fail to grasp the reality that while the ideals may be noble... their implementation has been corrupted by the Communists and Socialists among them who call themselves Liberals and Progressives.

Hollywood personalities are not Liberals... they are Socialists and they use their political influence to encourage Liberals to support their views. That is especially true of the young. The funny thing is that during the Red Scare, Liberal Democrats were the ones writing most of the Anti Communist legislation trying to purge the Communists and Socialists from their political ideology rather than just from the Democratic Party. When they essentially lost, that's when the Neocons began shifting to the Republican Party... but the Neocons at this time also called themselves Liberals interchangeably with Neocon because they began as Liberals and broke from the leftwing Liberals... Neocons are essentially rightwing Liberals which is why they support the welfare state, illegal immigration and respond to foreign political matters with military force or threats first before looking at diplomatic options... all things Conservatives do not support revealing that they have been infiltrated by foreign political views as well.

The problem is that Conservative actors in Hollywood are focusing their activities on their political views which include focusing on family, their careers and any social work they do is in person trying to accomplish things on their own rather than exploiting their fame to manipulate the masses.

If you examine most of the Liberals who promote their views to the masses, they're hypocrites who use their fame to manipulate their fans to do things or live their lives in ways that these celebrities themselves do not live their lives the ways they promote to others.

In regards to discerning reality... if you have rightwing corporations controlling and selecting leftwing media personalities who are causing them to lose hundreds of millions of dollars... it means they are using them purposely to destroy support for leftwing political views and to buy off leftwing politicians whom these leftwing personalities promote knowing these political leaders will have so little support overall that they will essentially destroy their credibility.
