They worry that people who act on their traditional, religious convictions about marriage are paying a price in the media and in state courts.

Conservatives are rallying around a House bill designed to protect religious people who advocate for traditional marriage — a belief, they say, that is held in increasing contempt.

But supporters of same-sex marriage say the bill actually protects the discriminators — individuals and nonprofits that would deny gay people benefits or services simply because they are married to a same-sex partner.

More than 60 House members — mostly (but not all) Republican — have signed on to the Marriage and Religious Freedom Act, which was introduced Sept. 19 by Rep. Raul Labrador, R-Idaho, who came to Congress in 2010 on a wave of support from the conservative Tea Party.

The bill signifies a shift in strategy for gay marriage opponents: Increasingly resigned to the reality that they’re unlikely to stop gay marriage, they’re now trying to blunt its impact by carving out explicit protections for dissenters.

“This bill affirms that a person’s religious belief in the importance of natural marriage should be treated with tolerance and respect by the federal government,” said David Christensen, vice president for government affairs at the Family Research Council, which is promoting the bill.

Labrador crafted the measure in the wake of June’s Supreme Court decision that struck down most of the Defense of Marriage Act, which had prohibited the federal government from recognizing same-sex unions. But the bill was also prompted by Internal Revenue Service scrutiny of the tax-exempt status of conservative groups — a controversy that came to a head shortly before the DOMA decision.

Under Labrador’s bill, no institution could lose its federal tax-exempt status because it promotes traditional marriage. Neither could the federal government deny a grant, contract or employment to a person or institution based on their belief that marriage should only be between a man and a woman.

“Congress needs to make clear that the federal government cannot punish people for their religious belief,” said Christensen, referring to the IRS controversy.

The National Organization for Marriage, Focus on the Family, the Southern Baptist Convention’s Ethics & Religious Liberty Commission, Concerned Women for America and the U.S. Conference of Catholic Bishops are also supporting Labrador’s bill.
