I don't agree with your premise that removing don't ask, don't tell equals permission to or the desire to flaunt homosexuality. I don't think that what gays are asking for. I think they just want to be able to fell safe, if asked, in responding truthfully that they are gay.
Imagine if it was the reverse. Would any straight person feel good about having to pretend to be gay in order to keep your job? I saw part of a TV documentary, (wish I could remember the title), where a highly decorated and clearly upstanding career officer decided he had to resign from the military because the obligation to go to great lengths to hide the fact that he was in a homosexual relationship was tearing him apart. It made him feel isolated from his his fellow soldiers and undermined teamwork. This guy was no over sensitive wuss. He had been in combat and performed outstandingly. But having to pretend he was straight was a travesty he could no longer put up with so he resigned and the military lost a good officer.
On another board I post on there is a poster who is a former marine who resigned from the Corps after a long service for the same reason. He said he couldn't lie anymore. del will probably remember him. He was a very eloquent writer and after reading his posts I could understand better how it can wrench a person inside to pretend to be something you aren't for no good reason other than to coodle a minority of homophobes.
