Update: this is a joke. Cpt Hill never said any of this. It was lifted from Col Jessep's monologue in the film A Few Good Men. It would be an appropriate response to Rick Santorum's answer to Cpt Hill's question, but it is entirely fictional. I'd thought it would be obvious, but it seems that quoting a movie that's almost 20 years old gets lost. I apologize to anyone who earnestly believed these to be Cpt Hill's words.
Stephen Hill's reply to Rick Santorum really ought to be:
Senator, we live a world that has walls, and those walls have to be guarded by men with guns. Who's gonna do it, you? You, Senator Santorum?
I have a greater responsibility than you can possibly fathom. You weep for Don't Ask Don't Tell, and you curse the military. You have that luxury. You have that luxury of not knowing what I know: that gays serving in the military probably saves lives. My existence, grotesque and incomprehensible to you, saves lives. You don't want the truth because deep down in places you don't talk about at parties, you want me on that wall, you need me on that wall.
We use words like honor, code, loyalty. We use these words as a backbone of a life spent defending something. You use them as a punch line. I have neither the time nor the inclination to explain myself to a man that rises and sleeps under the blanket of the very freedom that I provide and then questions who sleeps under my blanket. I'd rather you just said thank you and went on your way. Otherwise I suggest you pick up a weapon and stand a post.
