Don't Ask Don't Tell is such a stupid policy for the military. All 4 branches, most especially the navy (of course. It would be the navy) have lost thousands of their brightest and best qualified.
That said, it does bother me when people assume it's the military as an institution that is the sole and biggest reason for DADT. They are a reason, but it is instead the systemic homophobia among the rank and file that is the real issue. Homosexuals in the military are not numerous enough to protect each other, as racial minorites could when the forces were integrated. The military knows it doesn't have the ability to prevent violence, only punish it, IF they can prove who did it. Big If. Some specialties, usually the ones that require more skill, education, and intelligence, have a substantial number of gay servicepeople going quietly about their lives; I personally know a few. They do their jobs well, and do as all officers are encouraged: keep home and work separate. And most people know they're gay, but no one cares. But can you imagine life as a grunt or seaman? Ninth grade gym class all over again.

As part of my research on Matt Sanchez, a Marine Corps reservist whose gay porn and prostitution made news a while back (see URL link with this message), I took a close look at rules governing military discharges.

As a result, I have only limited sympathy with Jason Knight. While I strongly oppose DADT as unfair and illogical, I don't think he has acted particularly well.

Shortly after his wedding night, Knight informed his bride that he was gay and they annulled their marriage. At that point, Knight approached the Navy and told them he was gay. The Navy responded by seeking an OTH (other than honorable) discharge and seeking return of pay and allowances.

Knight appealed and won an honorable discharge. This had the effect of clearing any mention of his homosexuality from the Navy's records. That's why they recalled him -- voluntarily, which Knight says he wasn't aware of -- to service.

After being recalled, Knight again raised the issue of his honosexuality, this time through the media. And now he's been discharged again. The bottom line: He was able to keep his enlistment bonuses but not have to potentially face hostile fire during a time of war.

You'll have to forgive me for being less than thrilled here. I do think gay people should be able to serve openly, but there is something less than noble to me about Knight's tactics.
