Outgoing “Face the Nation” host Bob Schieffer yesterday wasted no time whatsoever in taking the fight to guest Tony Perkins, president of the Family Research Council. The peg for the interview was this week’s Supreme Court hearing on same-sex marriage. Schieffer:

Mr. Perkins, I’m going to say this to you upfront: You and your group have been so strong in coming out against this, and against gay marriage, that the Southern Poverty Law Center has branded the Family Research Council an anti-gay hate group. We have been inundated by people who say we should not even let you appear because they, in their view, quote, ‘You don’t speak for Christians.’ Do you think you’ve taken this too far?

No, came the answer from Perkins, who insisted that marriage between a man and a woman is “the cornerstone of society.”

Though Perkins thanked Schieffer for inviting him on air, today he released a statement that blasted CBS News. “[I]t was disappointing to see that any media outlet would rely on a group like SPLC that has actually been linked to domestic terrorism in federal court and traffics in politically-motivated, inaccurate, and biased claims,” notes the statement, in part. “After taking a deeper look at the SPLC’s motives, the FBI removed links to the SPLC from its ‘hate crimes resources’ page and the Department of Defense, along with the U.S. Army, have distanced themselves from SPLC’s materials.”

The reference to domestic terrorism appears to stem from the 2012 incident in which a man shot a security guard at the FRC’s Washington headquarters. Perkins, according to this account, said that the SPLC had given the man, Floyd Lee Corkins II, a “license to kill” in classifying FRC as a hate group. SPLC called the designation justified.

In his note, Perkins also ripped Schieffer for “actually” asking for evidence proving that same-sex marriage leads to discrimination against people of faith. Perkins responded by citing the case of Aaron and Melissa Klein, owners of an Oregon bakery who in 2013 declined to make a cake for a lesbian wedding on religious grounds. They face a damages judgment of $135,000 for their decision. “The media isn’t covering the stories of these victims — not because they don’t exist — but because liberals recognize their potential to swing the debate. The Left’s totalitarian tactics continue to trump the First Amendment rights of Christians who were fired, sued, harassed, fined, and suspended for their beliefs,” notes Perkins in his statement.
