Fox News hosts have used the controversy surrounding Rowan County, Kentucky clerk Kim Davis to repeatedly hawk the new book from a man considered one of America's most extreme and prominent anti-gay hate-group leaders.

Tony Perkins is the president of the Family Research Council (FRC), an organization that has been labeled a "hate group" by the Southern Poverty Law Center for spreading damaging lies about gay people, including the myth that they are more likely to engage in pedophilia.

Perkins' latest book, No Fear, was published on September 8 and tells the stories of “young people who have taken a stand for Biblical truth,” including Aaaron and Melissa Klein, the Oregon bakers who were fined after refusing to sell a wedding cake to a same-sex couple. The book is a collection of misleading culture war stories aimed at depicting conservative Christians as the victims of religious persecution by liberals.

That's a popular narrative on Fox News, so it's not surprising that the network has promoted the book repeatedly during its news programming, playing off the controversy surrounding Kim Davis, the Rowan County clerk who went to jail for refusing to issue marriage licenses to same-sex couples:

Fox's knee-jerk endorsement of Perkin's book is also self-serving: Perkins himself admitted that many of the stories in No Fear were pulled from Fox's reporting.

Perkins and the Family Research Council have long benefited from their relationship with Fox News. Todd Starnes, the network's serially misinformed culture war reporter, regularly turns FRC press releases into national news stories, while FRC touts the network's reporting to reinforce its Christian persecution narratives about LGBT equality.

Perkins has also found a close ally in Fox anchor Megyn Kelly, who has hosted the hate group leader more frequently on her show than any other Fox News program has, regularly giving his anti-gay extremism a veneer of mainstream credibility.

With Fox News giving Perkins free airtime to promote his book, the network has become both a political and financial asset to one of the country's most extreme anti-gay hate groups.
