Your age,nationality,Gender,Race,Physical appearance,Beliefs, Personality,Desires and thoughts none of these things are you. Your true self is beyond all of these things. All of what I said all of these stem from the ego which is your sense of self. Social conditioning creates the ego your sense of self comes from social conditioning and programming.
People are so defensive and get so angry when you criticize or challenge they beliefs because the beliefs give them that sense of self. That’s why when someone’s belief is shattered it can lead to a mental breakdown and identity crisis where they are lost because they sense of self was basically destroyed. That belief created they reality. Their is a difference between a belief and a known. I say be open minded but that’s a very hard thing for people especially guys to be. I have my deepest conversations with girls they tend to be more open minded.
