Ere yees still going on about what a young lad said in a war zone? Terminology regarding the enemy is a long "tradition". It's almost necessary for the dehumanizing of one's adversary. After all, if you called the lad across the way Scooter or Bubbles or some other inane affection, would it not be just a tad harder to fix bayonet and run him through?

Come, come, now. Get a grip. Send a wee lad into battle and expect him not to deal with killing and death in whatever way he can? Name calling is one of the basics of dehumanization of the enemy. How else can you kill Theodore? That rat bastard with the button eyes?
