Peter Sprigg of the Christian conservative Family Research Council (FRC) has called Tuesday's repeal of “Don't Ask, Don't Tell” a “sad day.”

The military policy that banned gay and bisexual troops from serving openly ended on Tuesday, nearly 18 years after its implementation and 9 months after Congress authorized its repeal. More than 13,000 service members were drummed out of the military for violating the policy.

During an appearance on the Christian Broadcasting Network (CBN), Sprigg said he feared for Christians serving in uniform.

“I think this is a very sad day in American history,” Sprigg said. “I do fear the consequences. I fear the consequences in terms of sexual tension, sexual harassment and even sexual assault. I fear the threat to freedom of speech and religious freedom for those who disapprove of homosexuality. And I fear that this will cost us in terms of personnel, both in the areas of retention and recruiting.”

Troops coming out will lead to “a situation where we have sort of reverse discrimination and it will be those … who hold traditional values and disapprove of homosexual conduct who will be in the closet and forced to remain silent.”
