Tony Perkins, president of the Christian conservative Family Research Council (FRC), has claimed that President Barack Obama is attempting to “eliminate” Christianity through his support for LGBT rights.

In a fundrasing letter, Perkins asked supporters to contribute to his organization “before it is literally too late.”

“[S]ame-sex 'marriage' is not the ultimate issue,” Perkins said in the email, a reference to Friday's Supreme Court ruling striking down state bans on gay marriage. “It is a stepping-stone. The real issue is the Obama administration's dogged determination to eliminate anything and everything that stands in the way of the President's radical agenda. Silence is dissent. And to do that, you punish speech – and belief.”

“Orthodox Christianity's truth doesn't change, and as long as we remain tethered to this transcendent, unchangeable truth, we are a problem for them. If you can't change it, you must eliminate it. Which is what they are seeking to do.”

“With the Supreme Court ruling to redefine marriage, things are going to get rough for Christians in America,” he added.

In an interview with Philip Klein of the Washington Examiner, Perkins claimed that gays “have always been able to do what they want in the privacy of their own homes.”

In fact, it was as recently as 2003 that the Supreme Court struck down sodomy laws in 14 states in Lawrence v. Texas.
