I'm not just talking about the news shows, here! How much of entertainment contains fake and fictional right wing politics

Does it ever end? How much does it cost to keep TV, Facebook and the entire web from reflecting the real politics of the real majority to the people?
For the example free readers who might care-. Like the way they NEVER smoke pot on "Friends", "The Big Bang Theory", "Frasier" or wherever...? The way nobody EVER objects to the car culture?
