I think what you mean with “open mind” is not what I think of. To me that would include (the possibility of) accepting their way as “correct”, so to accept their concept of reality. Like in a debate about how much wine is good (if) and when it starts to be bad. But objectively wrong things are not something I need to be open about. I can discuss it with someone without dismissing their view etc. but I would never be open minded about it.
