The Fariness Doctrine is to allow other opinions on the air. The FCC is supposed to be handing out licenses with the caveat that the broadcasters do so in the interest of the public. If you're old enough you would remember the day when there were Free Speech Messages... Air time provided for free to citizens to express their viewpoints on political, economic, or other issues of public interest. That used to be required by law. That was struck down by the Telecommunications Act, along with the restrictions established to prevent media monopolies. Free marketers don't think far enough ahead to realize that the system they support fosters monopolies, and those serve no one but the monopoly themselves.
