What is arrogance? Understanding the ego's main defense mechanism

[Zion]

I recently recommended a couple of your videos to some of my family recently, & they ended up skimming through the videos I sent, making extremely arrogant & poor assumptions about your concepts. I sent one of them your "What is the Devil?" video, & one other; "Making sense of psychedelics". I'm curious about your thoughts on the topic of arrogance/ignorance, why it is so prevalent in our culture, how to understand it, & how you would go about transcending it. I would love to have the knowledge to be able to dissect arrogance when I see it, & find out where its coming from. All replies appreciated!
