The National Organization for Marriage (NOM) has called on members to support a proposed GOP bill which seeks to allow adoption agencies to exclude gay couples.

The Child Welfare Provider Inclusion Act of 2014, introduced last week by Republican Senators Mike Enzi of Wyoming and Mike Kelly of Pennsylvania, would allow faith-based agencies opposed to marriage equality to deny service to gay and lesbian couples.

Catholic-based agencies in several states have decided to shut down their adoption and foster care programs rather than place children with married gay couples.

“Faith-based charities and organizations do an amazing job of administering adoption, foster care and a host of other services,” Enzi said in a statement. “Limiting their work because someone might disagree with what they believe only ends up hurting the families they could be bringing together.”

The Human Rights Campaign (HRC), the nation's largest LGBT rights advocate, said the proposed legislation would allow “rampant” discrimination.

“It's increasingly clear that, post-Hobby Lobby, some in positions of power believe that religious freedom should only belong to a few,” HRC's Ellen Kahn said. “If this bill passes, an Evangelical straight couple, a single father, or a committed and loving gay and lesbian couple could find their path to adoption blocked for no reasonable reason other than naked discrimination.”

In a blog post titled This “Common Sense Legislation” Needs Your Support, NOM President Brian Brown applauded the bill.

“Believing that kids need both a mom and a dad should not disqualify a service provider from doing their invaluable work,” Brown said. “They shouldn't be penalized by the revocation of aid for holding to the common sense principle that children do best when raised by both a loving mother and father.”
