Jezebel has the full text of a letter sent by an anonymous gay soldier leaving to serve in Afghanistan.  Please click over and read the whole thing, as it is incredibly moving and really drives home what this debate is all about:

The silence is the hardest part. I listen intently as my fellow soldiers talk about facing the reality of leaving their loved ones for a year and all the life events that will be missed. I don’t talk about my own experience at all, because it’s easier to come across as cold and removed than to risk slipping and mentioning that my loved one is of the same gender. For all I know, there are other gay soldiers in my unit, ones who understand what I’m going through. My gay friends in civilian life are supportive, but they don’t often understand the military or soldiering. That camouflage is another burden I carry as I prepare to leave.

[...]

I am angry at the politicians who have for several years talked the talk on the policy, heightening the awareness of homosexuality among military personnel, and then done little to nothing to actually change it. We gay soldiers are the ones who suffer but can’t openly participate in the debate.
I am angry at certain senators -– John McCain comes to mind –- who have obviously lost touch with any understanding of the current generation of service men and women, who, as we all know, support repeal at overwhelming numbers. They hide behind a vitriolic rhetoric fraught with illogical arguments and innuendo, smothered by their obvious fear.

[...]

And I’m reminded of the moral courage of my partner, who encourages me everyday to continue to put on that uniform; who believes that some things are worthy of our energies; who quietly plods along and prepares for my deployment as I do the same. I know as a soldier, it is the people we leave behind who bear the real brunt of deployment, who hold it all together, who send the care packages and pray for our returns. He’ll have to do it on his own though. There are no support groups for the gay partners left back home.

That’s just three random paragraphs I decided to excerpt. Read it all, please.
