But as soon as you start targeting civilians you are nothing but a cowardly piece of (explicative for feces) and I will NEVER listen to your justification, or lend any credence to your complaints.
target the government and you're a freedom fighter. Target civilians, and you're just a murderous piece of (explicative for feces)
