I'm ignorant with regards to a great many subjects in life and frankly, freely admit to being wrong far more often than being right and certainly never pretend to be right if I am aware That I would have to pull shit out of my ass to pretend I have something meaningful to contribute. It is for these precise reasons I admire anyone who can teach me anything, regardless of who they are or what the lesson is. There are many posters on this very forum for whom I hold the same admiration and express my gratitude for sharing their knowledge. I don't know anyone on this forum personally but compassion still inspires me to post my condolences should any ill fortune befall them, even if I don't like the person or disagree with them.
But if you are the sort that can't grasp the gratitude someone feels toward anyone who has taught you anythimg you might consider valuable, then IMO you have no true sense of value for shared knowledge.
