“People then form their judgment on what they think of X and Y.”
                                        
                                        John Boone 
Red Mars (1992) 
Context: The only part of an argument that really matters is what we think of the people arguing. X claims a, Y claims b. They make arguments to support their claims with any number of points. But when their listeners remember the discussion, what matters is simply that X believes a and Y believes b. People then form their judgment on what they think of X and Y.
