Richard Land, president of the Southern Evangelical Seminary and a former Southern Baptist Convention official, has called on Christian conservatives to stand up to the “gay thought police.”

While guest-hosting FRC's Washington Week radio show on Tuesday, Land spoke with Fox News' Todd Starnes about President Barack Obama's recent executive order that prohibits federal contractors from discriminating against employees on the basis of sexual orientation and gender identity.

In a post, Starnes accused the Obama administration of being “hell-bent on forcing Christians to assimilate to the military LGBT agenda.”

“If you cross the gay thought police, you're in trouble,” Land told Starnes, who was lamenting that too many pastors refuse to speak out.

“And Todd, you know what my answer to them is?” Land rhetorically asked. “It's the answer that was given by the Lutheran pastor [Martin Niemoller] back when the Nazis were in control of Germany: 'First they came for the communist, I didn't do anything because I wasn't a communist. Then they came for the labor union leaders, and I didn't do anything because I wasn't a labor union leader. They came for the Jews, I didn't do anything. Then they came for me and there was nobody left to stand up for me.'”

“Don't think because you're passive and because you're quiet they won't come after you if you dare stand up and preach your convictions,” he added.
