Two conservative groups opposed to gay rights are asking ABC to abandon plans for a sitcom based loosely on the life of gay rights activist, sex advice columnist and author Dan Savage.

The Media Research Center (MRC) and Family Research Center (FRC) are behind the effort to kill the series, tentatively titled The Real O'Neals.

“Dear Mr. [Robert] Iger,” begins a postcard the groups are asking members to sign. “ABC plans to release a pilot sitcom based on the life of radical activist Dan Savage. Dan Savage is a hateful anti-Christian bigot. I am asking for ABC and its parent company Disney to cancel this pilot sitcom immediately.”

According to the groups, more than 21,000 postcards have been sent. Another 4,000 telephone calls to the network have been placed.

The Hollywood Reporter described the comedy as centering “on a picture-perfect family that is turned upside down when the youngest son comes of out the closet. What seems like the end of their idyllic life turns out to be the beginning of a bright new chapter when everyone stops pretending to be perfect and actually starts being real.”

Savage told The New York Times, “it wouldn't be accurate to describe [the project] as autobiographical,” though he acknowledged it evolved out of a meeting he had with executives and he's acting as an executive producer on the series.

MRC President L. Brent Bozell said that the network was aligning itself with Savage “not because he's gay” but because of his “religious bigotry and personal offensiveness.”

“There are a thousand and one gay people they could have chosen,” he said.

Savage is known for going after high-profile celebrities and politicians who oppose gay rights, including Dr. Laura, Mike Huckabee, Rick Santorum and Michele Bachmann.

He called the campaign to end the show “misdirected.”

“[T]he show isn't by me – I'm not one of the writers – and it isn't about me,” Savage said.
