@drdewaynelehman What, in your mind, is the difference between discussion?
When I read attempts to differentiate these two ideas, discussion includes a willingness to listen, learn, and possibly change one's view, which, at face value, appears (to me) to be the opposite of what you just wrote. But I could be wrong.
For the record, I do care if someone disagrees with me. I don't know everything, and respect others who can teach me things. Hence, mixing it up here on a social media site.
