Peter LaBarbera, president of Americans For Truth About Homosexuality (AFTAH), on Thursday chided ex-gay activists who have denounced the “ex-gay” movement they once led.

Recently, nine former leaders of the “ex-gay” movement, including Yvette Cantu Schneider, former executive director of Living in Victory Ministry, denounced attempts to alter a person's sexuality from gay to straight as “ineffective and harmful.”

Others have also come forward, including Alan Chambers, the former president of controversial “ex-gay” Christian therapy group Exodus International and Randy Thomas, a former executive vice president at Exodus.

Speaking on Janet Mefferd's radio show, LaBarbera described the ex-ex-gay activists as “sellouts” who are “negating the word of God to score some points with the politically correct thought police” while hurting “people trapped in homosexuality.”

Randy Thomas “needs to apologize to the body of Christ now for selling out the Bible,” he said. “That's an apology I want to see from Alan Chambers and Randy Thomas and all of these sellouts, is people saying I'm coming back to this route and then apologizing to the body of Christ for promoting error.”

He added that Schneider's apology was “very sad.”

“This one is a stab in the back to all of her pro-family friends. And I pray that Yvette will turn back to the Bible and turn back to God and apologize for this apostasy,” LaBarbera said.
