So it's a long read in four parts, but bear with it.
This is a blog post by a now-openly gay marine in a post-DADT world and taking his first proper date to a military function. It's a nice uplifting story for one thing, and also offers some nice insights into the kind of things gay servicemembers, have, and continue to suffer due to the DADT policy, and to what extend they are changing.
