What to do if you find yourself in a conversation with someone who doesn't believe we should retaliate for the terrorist attacks.
1. Engage in conversation, and ask if military force is appropriate.
2. When he says "No" ask, "Why not?"
3. Wait until he says something to the effect of "Because that would just cause more innocent deaths, which would be awful and we should not cause more violence."
4. When he's in mid sentence, punch him square in the face.
5. When he gets back up all pissed off, point out that it would be a mistake and contrary to his values to strike you, because that would be awful and would be "more violence".
6. Wait until he agrees, and has pledged not to commit additional violence.
7. Punch him in the face again, harder this time.
8.Repeat steps 5 through 8 until he understands that sometimes it is necessary to punch back.
