I'm not going to say it was the logical answer to the situation, but it was totally satisfying to end a conversation that way.
I played through Mass Effect once already, straight through the story, and did it all Light Side like. well, now I'm playing back through it as a ruthless renegade chick I just called Sniper, cause thats the main reason I made another character, I wanted a sniper rifle. right now I'm going to every planet in the galaxy that doesn't have to do with the main plot, and you run into a lot of stuff like this.
Renegade (Dark Side for you KotOR people) just gets things over with, while letting you be a jerk and kill everybody, yet still get commended for your actions by the Alliance military. I don't have to go through insanely long dialogs to get on someones good side, I just abuse the "intimidate" function.
you feel more emotionally attached to your teammates if you play Paragon (Light Side) and get super pissed when they *spoiler* start dying on you one by one. I lost some of my best squad-mates because of situations that could have been avoided earlier in the game*end spoiler*
but when you play Renegade, so long as your best two gunmen are alive, who cares, the rest of the crew can have "accidents" that might leave them floating in the void.
 also, I really don't like Ashley, but I keep her around cause she's got a sniper rifle. as soon as I can equip Wrex with one, she's gone.
