From Amazon's product description:
In today’s partisan world, where media provocateurs rule the airwaves and political correctness dictates what can and cannot be said with impunity, Williams shows how the honest exchange of ideas and the search for solutions and reasonable compromise is deliberately muzzled. Only those toeing the party’s line—the screaming voices of the extremist—get airtime and dominate the discussion in politics and the media. Each side, liberal and conservative, preaches to a choir that revels in expressions of anger, ideology, conspiracies, and demonized opponents. The result is an absence of truth-telling and honest debate about the facts.
