Sorry to bring this back from the dead, and please correct me if I'm wrong but, I'm guessing that you have not got much personal experience with LGBT issues. I think it is worthy of a place in war stories, because military organisations are one of the least accepting places. To give a few examples, during the second world war, there was a British mathematician called Alan Turing. He was responsible for saving hundreds of lives by cracking German codes. He also happened to be homosexual, and after the war he was convicted of "gross indecency" sentenced to chemical castration and eventually driven to suicide. Until relatively recently LGBT people were not allowed to join the armed forces. Even today, there is a much greater stigma in military life than civilian life, especially for transgender people. These aren't issues that can just be forgotten. I'm not saying make a huge fuss over them, I'm just saying that celebrating the fact that, in our story, these issues have been overcome and all people are finally accepted should not be suppressed because it doesn't quite fit with a minor aspect of the lore.
Before dismissing LGBT issues entirely, walk a mile in these shoes.
