Your question is a little unclear.
If you’re talking about a debate, or needing to approach someone about something, it’s best to go in as prepared as possible and address any new arguments as they come.
However, the other person has to feel like they’re being heard, understood, and (often) validated in some form—even if it’s not completely genuine—if there is ever a chance of getting them to change their mind.
If this is a personal (or professional) conflict, though, be careful. To some people, it doesn’t matter what you say or how you say it, even if they’re in the wrong.
