Three leading gay groups have banded together to urge advertisers to walk away from advertising on Fox News.

The group Equality Matters for America kicked off its Drop Fox campaign by appealing to gay-friendly travel site Orbitz.

“Orbitz risks alienating gay and lesbian customers by giving ad dollars to Fox News, a network that blatantly promotes an anti-gay political agenda,” Llyse Hogue, senior adviser at Media Matters for America, said in a statement. “Orbitz customers who value equality can and will take their business elsewhere, and this is just the tip of the iceberg. Any company whose customer base values the diversity, civil rights, and journalist standards should recognize that doing business with Fox will only cost them in the long run.”

Gay media watchdog GLAAD and the California-based Courage Campaign are also backing the campaign.

At the website, the groups argue that Fox News has compromised its journalistic integrity to promote an anti-gay agenda.

Some of the examples given are the promotion of anti-gay Fox hosts Mike Huckabee and Bill O'Reilly, the network's claim that gay servicemembers represent a threat to troop morale, and providing a platform for anti-LGBT extremists.
