Is being "open-minded" a good thing?
"Openness used to be the virtue that permitted us to seek the good by using reason. It now means accepting everything and denying reason's power."
Christians should be openminded in the sense of not exalting ignorance. But we should avoid the cultural peer pressure to say with a smile that everyone's values, religion, and morality are equally valid. This path only leads to self-contradiction and ultimately despair. Jesus offers a better way and has the authority to make it available to all who would take him at his word. "I am the way, the truth, and the life." (John 14:6)
