#4 Respect other's opinions.

This sets the scene that promotes conversation and real communication and creates an environment that is supportive and non threatening.  Wouldn't it be wonderful to never be put on the defensive for your thoughts and ideas?  Where those thoughts and ideas develop into discussion is the objective.  Everyone has something to contribute.  It's okay to disagree, but there is a way to do so gently without hurting feelings or making someone feel doubtful about themselves.  Appreciate without being condescending.  Disagree without being condescending.  Be open to discussion and you will be surprised how others jump into the conversation comfort zone.
