Lesson #1: always agree with my side of the argument... (no, support what you think is right)

#2: If in a debate, always have a good source to include with your post.

#3: Use 'when did you stop beating your wife' questions. That often gives you the edge in those kind of issues, since the opposite side does the same thing.

#4: Focus on the strongest pieces of the argument first and don't try to push something that people don't seem to agree with. They will chew you out with something that they don't like

#5: People are often biased. Take these suggestions while keeping that in mind.
