From pg via HN

• DH0. Name-calling. Standard trolling moves.
• DH1. Ad Hominem. Something like labeling other people.
• DH2. Responding to Tone. This happens a lot. I have similar experience on maillists. No matter how interesting your questions are, many replies are about how ignorant your are in related theory.
• DH3. Contradiction.
• DH4. Counterargument.
• DH5. Refutation.
• DH6. Refuting the Central Point.

I must check rhetoric books for more example :)
