Even if we relax this discussion to non-terminal impacts, it is quite literally optimal to just allow people this dignity. The energy it takes to enforce every definition as your own is unsustainable. If two people cannot agree on basic definitions, there is no chance for valuable discussion anyway. The most basic definition that exists in an argument is the parties involved. Disagreeing on that basis invalidates everything downstream. So--if one is arguing in good faith, it costs almost nothing, and you gain a lot, to simply allow the other party to define themselves.
