This one came across my email today.  Just the thought of trying it out kept me amused for quite some time.

Subject:  Force is Necessary

How to teach a naive, hemp-shirt-wearing college idiot that force is sometimes needed.

1. Approach student talking about peace and advocating negotiation.
2. Engage in brief conversation, and ask if military force is appropriate.  When he says No, ask, Why not?
3. Wait to hear:  Because that would just cause more innocent deaths, and it would be awful and invite more violence.  When he is in mid-sentence, punch him hard in the face.
4. When he gets back up to punch you, point out that it would be a mistake and contrary to his values to strike you, as that would be awful and invite more violence.
5. When he agrees and pledges not to commit additional violence, punch him in the face again.  Harder if possible.
6. Repeat steps 4 and 5 until he understands that there’s just no negotiating with some people.

Somebody I forwarded that to responded that all is fine until I attract the attention of a police officer.  True enough.  But if I resisted arrest, the police officer would give me a lesson in violence, thereby proving my point.
