Debate not fighting
All debates are arguments, not all arguments are debates. We aren’t here to address mindless shouting or simply attacking the other person. In a debate each side has a specific claim they’re trying to defend and advance, and is putting forward evidence for their side or rebutting evidence on the other side.
Why debate?
When two people disagree, why should they bother talking through the merits of each argument and trying to solve it? Why not just shrug, agree to disagree and move on?
