Making a Strong Rebuttal: Answer the Argument, Not the Person
A good rebuttal makes the other person's argument better before it takes it apart. Here is a simple way to do that.
1. Say what they claimed
Restate the argument in a sentence. If you cannot do that fairly, you are not ready to answer it yet.
2. Find the weak link
Most arguments fail in one of three places: the facts are wrong, the reasoning does not follow, or something important was left out. Pick one and aim at it.
3. Bring evidence
Back your point with something other people can check. An example, a figure with its source, or a clear piece of logic is better than a stronger tone.
4. Leave the person out of it
Attacking the writer instead of the argument loses the point and the audience. Keep it about the idea.
Next time you reply to someone, try following those four steps in order. It is surprising how often it changes the whole tone.
