It will not contain therein space for alternative thoughts on the main point let alone space for any alternatives for any unexamined assumptions.
Truth is multidimensional and fairness impossible to determine to everyone's satisfaction. For example 2 people discussing the best way to travel around the world are unlikely to find agreement with someone who believes the earth is flat and impossible to fly around and 2 different types of dating artifacts are equally meaningless to someone who believes the earth is 6000 years old.
Alternative viewpoints can find themselves a home in the comment section or if undesirable there on your own home on the web.
Wherein the web isn't censored in a heavy handed fashion we have the most reasonable answer to the fairness doctrine. Everyone can be heard but not everyone will find an audience that desires to listen.
