Maybe the folks working to end DADT ought to draw attention to the folks who abuse DADT. This is from a lesbian in the military:
Looking for a way out of the service isn't a new idea. Since 9/11, soldiers have been going to extraordinary measures to find the quickest way out of a deployment including intentional pregnancies and cutting off fingers. Hell, my unit's chaplain (who was gay, by the way) went AWOL! He ran away with his lover to Canada the night before we left for Iraq. That's a nice morale booster for the soldiers.
During my time in the Army, a large percentage of the DADT investigations were caused by straight soldiers playing the homosexual card to get out of going overseas. These guys would go to the extreme, staging photographs and videos of themselves with other men, or maybe even making out in front of their commander. They were using DADT as a potential free ticket out of a deployment.
Last year I was talking to a single, straight man in the military who was complaining that he got deployed three times more than other officers in his unit because he was single and didn't feel like coming up with an excuse to get out of something he signed up to do. There was still bitterness, though, towards women he said would start a family to get out of deployment, married men who would say that their wives had "mental health issues" that could never be diagnosed so they needed to stay home and care for them, an officer who herself developed a series of undiagnosable maladies, preferential treatment to folks with "families," and colonels sending assignments they were more qualified for down the chain of command.
All because, deep down inside, many people who join the military really don't want to go to war.
Personally, I don't have much sympathy for folks who signed up for the military post-Iraq but don't want to be deployed. They knew what they were getting into. The war in Iraq wasn't a secret operation. Sure, with unemployment rising for young people to astronomical levels, the military might be their only option, but if someone's taking a discharge over a deployment, then they don't really think they need the job.
That said, that doesn't mean that there aren't a lot of people looking for a way out of a deployment when reality comes crashing down on them that they might actually have to go fight in a war. The recruiting officer might have told them that there's a base a couple miles out of town, and, after bootcamp, who knows, maybe they'll be stationed there. They'll be able to visit their high school friends after work and their aunts every other month. Joining the military is no big deal, and, besides, who else is going to give someone with no experience, no marketable skills, a high school education, and possibly a criminal record a full-time job with health care in this economy?
Unlike other assured discharges, you don't have to really break the law to get out under DADT. You don't have to risk prison time or hurt someone or get a criminal record. If anything, when people ask you why you got discharged, you'll probably just get sympathy.
And, unlike an actual mental or physical illness, a doctor is never going to be able to tell that you're not really gay. You say you like people of the same sex? Who am I to say no?
It'd be another argument to get rid of the policy, one that goes past those that are sympathetic ("DADT discriminates against LGB soldiers and takes away their jobs") and those that play into America's fetishization of the military ("Gay soldiers should be allowed into the sacred institution of the military because they can serve the country with honor") and goes straight to the interests of the people in charge of the military.
A friend of mine years ago predicted that DADT would be repealed when they couldn't find enough people to go to Iraq, but the military has been facing recruitment shortages for years (not this year, though! Thank you, Gramm-Leach-Blily Act) and Congress is just starting to show signs of wanting to repeal the ban.
But what if stories of people faking being gay to get discharged were publicized? Instead of talking about gay and lesbian soldiers defiling the purity of the military or a discriminatory policy defiling America's aspiration to be a nation of tolerance and equality, the narrative would become that of dishonest soldiers defiling the sanctity of DADT for personal gain.
At least it speaks to the interests of those in power. They obviously don't mind losing a few queers, but if the fact that it's already a "get out of the military" free card because it doesn't leave people unemployable anymore became better known, it might change minds.
