That's why Satan got thrown out of Heaven. It's called Pride and Arrogance. We all want to be the one in charge and the right one. We don't like other people getting one up on us. It is the number one flaw in humanity. It happened in the Garden of Eden, and it won't go away until God eliminates it.
What is the main lesson Jesus taught? There is a mis-quoted, verse from the Bible, that says, "Do unto others as you would have them do unto you." This verse simplifies the lessons of love and humility. Only we learn these, we can actually converse in a civil and respectful way. In other words, "I love you man, but we are just going to have to agree to disagree." I've had friends all my life that I disagree with. The problems come when the people I talk with aren't my friends, but someone I work with or have just met. Under a challenge of their way of thinking, defenses go up, because I immediately become a threat. I may destroy their entire belief system. That would make me superior in their eyes, something which they won't allow.
Hope this helps.
