You don’t understand a debate until you can argue the other side well enough to make them nod.

Understanding a disagreement means being able to state the other position in a form its holders would recognise and approve. Anything less and you are arguing with a cartoon you built yourself, which is easy to beat and teaches you nothing. Most confident opinions belong to people who have only ever met the weak version of the other side.

Before your next strong opinion goes public, write the best case against it in three sentences. Try them on someone who actually holds that view and see if they nod. If they correct you, you have just found what you were missing.
