This posts resonates with me a lot because i have been in situations where i was the least smartest person in the room and it felt intimidating. Even within circles here on the hive blockchain, there are people who are haughty and condescending and i avoid such crowds (even though i can behave in a similar fashion sometimes).
Creating the right atmosphere for learning and conversation is important to our individual and collective growth. Most times we silence people and miss out of the opportunity to bring about real change.
For me, the best kind of teaching — and learning — tends to be a dialogue in which both (or more) parties come away with better overall wisdom and information than they had before. Both the teacher and the student(s) are wiser.
Being arrogant about "what you know" and biased against those who don't know is pretty much a closing of the door that leads to strife and unrest... I try to avoid that!
