If conversations with this one person are frequently reaching the point where things like that are being said, it seems pretty clear cut: you should honestly just avoid any of the topics that have resulted in debates with this person.
It doesn’t necessarily mean you can’t talk to them about other things or that you can’t be friends (although it might).
Not every relationship has to allow for talking about all topics.
Sometimes being right isn’t actually important and can actually be counterproductive with certain people/topics.
