An article titled "Viewpoint Diversity" Requirements as a New Fairness Doctrine is forthcoming in the George Mason Law Review. A draft of the article is available, and feedback is welcome.
A PDF version of the draft is available, including footnotes. The article draws an analogy between the Fairness Doctrine and viewpoint diversity requirements.
One of the problems with the Fairness Doctrine is likely to also arise with viewpoint diversity requirements, as explained in the article.
