If I try to discuss news or issues with anybody who cannot/will not ever acknowledge a criticism or constructive feedback of their position, I know this is a not a healthy conversation. That does not mean they have to agree with me now or ever, but rather I can hear their position and they provide me some information to support what they are saying so I can have something to consider and learn more about. And I must do the same. Discussions are give and take and the learning and investment needs to go both ways.
