Christian conservative group One Million Moms is protesting lesbian drama The Fosters for trying to “desensitize America and our children by promoting inappropriate behavior.”

The Fosters stars Teri Polo (Meet the Parents) and Sherri Saum (Rescue Me) as a married lesbian couple who are coping with raising three children when a wayward teenage girl – a foster child – is added to the family. The show from executive producer Jennifer Lopez premiered Monday on cabler ABC Family.

One Million Moms urged supporters in a blog post to contact the show's advertisers and demand that they pull their spots from the program for “attacking my faith, morals and values.”

Advertisers are urged to distance themselves from “a controversial subject that your company would probably not desire to be associated with.”

“Urge advertisers to place it on their 'do not advertise' list in protest of the attempt to desensitize America and our children by promoting inappropriate behavior on a family channel,” the group wrote.
