NEW YORK (AP) – Critics of the military’s “Don’t Ask, Don’t Tell” policy are gaining new allies, including a few conservative Congress members and a West Point professor, as they press on multiple fronts to overturn the ban on openly gay, lesbian and bisexual service members in the armed forces.

As part of their strategy, opponents of the policy are now highlighting the ongoing struggles of Army and Marine recruiters. The Servicemembers Legal Defense Network say in a new report that many highly trained specialists – including combat engineers and linguists – are being discharged involuntarily while the Pentagon “is facing extreme challenges in recruiting and retaining troops.”

On other fronts:

-A federal court hearing is scheduled in Boston next month on a lawsuit by 12 former service members challenging the 12-year-old policy.

-In Congress, four Republicans – including stalwart conservatives Wayne Gilchrest of Maryland and Ileana Ros-Lehtinen of Florida – have joined 81 Democrats co-sponsoring a bill to repeal the policy. Gilchrest, a former supporter of the ban, said he changed his view partly out of respect for gay Marines he served with in Vietnam and for his brother, who is gay.

-A U.S. Military Academy professor, Lt. Col. Allen Bishop, wrote a column this spring in Army Times urging Congress to repeal the ban. “I thought I’d get lots of hate mail, and my colleagues would walk on the other side of the hall – but there’s been none of that,” he said.

Still, neither the White House nor the Pentagon has given any signal that they would drop their long-standing support for the policy, implemented in 1993 under the Clinton administration. It prohibits the military from inquiring about the sex lives of service members but requires discharge of those who acknowledge being gay.

On July 6, the Bush administration plans to ask a federal court in Boston to dismiss a lawsuit challenging the policy. The suit cites a 2003 Supreme Court ruling that state laws criminalizing homosexual sex were unconstitutional; the government says that landmark decision has no bearing on “Don’t Ask, Don’t Tell.”

More than 9,400 troops have been discharged since the policy was implemented. Discharges peaked at 1,227 in 2001, and declined to 653 last year, a drop which critics attribute to reluctance by war-zone commanders to deprive their units of experienced gay and lesbian personnel during difficult missions.

A Pentagon spokesperson, Lt. Col. Ellen Krenke, noted that dismissals under the policy are only a small fraction of overall military discharges. She also noted that the Defense Department could only change the policy if Congress acted first.

Gilchrest, the Maryland Congress member, said he was unsure how many of his fellow majority Republicans were ready to join in seeking repeal, but suggested the momentum was shifting in that direction.

“When this issue comes up, members who believe that gays shouldn’t be in the military are now more hesitant to voice their opinion,” Gilchrest said in a telephone interview. “Many of us who feel the other way have come out of the closet, so to speak. A year ago, I would have been uncomfortable expressing my feelings.”

Bishop, who teaches philosophy at West Point, said he had been troubled for years by “Don’t Ask, Don’t Tell” before deciding to write about it.

“They can be gay, but they can’t practice being gay. They can be here, but they can’t tell you who they are – it seemed pretty confusing to me,” he told The Associated Press.

In his Army Times article, Bishop assailed the policy as contradictory to fundamental American principles.

“Despite our government’s claim of liberty for all, we leave homosexuals out,” he wrote. “If the American military sees and is allowed to see itself as the protector of some but not all Americans, democracy fails.”
