How fair rally is the so called "Fairness Doctrine"?

Lets say you own a movie theatre and want to show only family oriented PG rated movies. Does the "Fairness Doctrine" then dictate that you have to show an equal amount of R or X-rated movies ? What if you owned a religious oriented radio station would you have to share equal time with atheists? How about print media if a newspaper writes 20 stories about Obama does it have to write an equal amount about a conservative politician? Or lets say you are having a political discourse amongst friends does it mean you all have equal time to express your particualar view? Is that fair enough?------------If government wants a fairness doctrine let them start with their own radio station NPR then we can talk about the rest !
