Tony Perkins, the president of the Family Research Council (FRC), has accused the White House of discriminating against anyone who preaches against sexual immorality.

In referring to Pastor Louie Giglio's withdrawal from President Barack Obama's second inauguration, Perkins said the Left will accept nothing less than “one hundred percent capitulation” from Evangelicals on homosexuality.

“As we learned yesterday, liberals are no longer satisfied by the church's silence on homosexuality,” Perkins said in a statement. “They will accept nothing less than the active embrace and celebration of what the Bible calls sin – or use totalitarian tactics to get it. What was once outrage over Christian activism has been replaced by outrage over Christian association. The White House has declared that anyone who holds to the belief – spoken or unspoken – that sexual immorality is wrong has no place at democracy's table.”

“This should be a wake-up call to every evangelical who thinks they can pacify the Left by making the symptoms of immorality their sole focus and being silent on the cause: sin. As those who seek to emulate Christ, our approach must be holistic. We should help the hurting regardless of the cause, but we must also have the courage to go beyond the symptoms to the source. Engaging the world through social justice or conservationism may help us find common ground – but it will not mollify faith's detractors. Nothing less than one hundred percent capitulation will.”

Giglio, of the Georgia-based Passion City Church, had been selected to deliver the inaugural benediction but withdrew after reports surfaced that in the mid-1990s he advocated therapies which claim to “cure” gay people's sexual orientation and called on Christians to prevent the “homosexual lifestyle” from becoming accepted in society.

On Thursday, Giglio, acknowledging the sermon, said he had a right to “hold differing views” and withdrew his name.
