Nope, I despise the enemy (Romney) so much that I’ll use an enemy weapon found on the battlefield against him.
So, if the Afghans in your unit begin to attack you, and the the closest weapon is a captured Taliban AK47, I assume you will refuse to use it. Is that right?
We’re not in a gunfight xzins and to use part of your analogy, there are plenty of weapons laying around called “facts” that do not require collusion with the real enemy.
