People throw around the term “open-minded” with the wrong meaning. Truly open-minded people know what they believe and why, know there are things they don’t know (a very Rumsfeldian idea), are willing to learn new things, and if those new things impact their current beliefs, then they are willing to change their beliefs. They also have the capacity to understand that people with differing beliefs and understandings can come to those in a logical, thinking manner, and they can respect those differences without feeling the need to embrace them.
