I used to be very blind to my “us vs them” thinking. I liked thinking I was open and accepting. Without going into details I discovered my capacity for being prejudice. I came face to face with both my internalized and externalized racism, misandry, misogyny, cacomorphobia, and homophobia. It was subtle, learned, and ugly. It became very clear to me that I needed to deeply evaluate my worldview of self, divinity, and others. I spent several years digging up the roots that separated me from others and kept me from moving beyond empathy into shared transparency.
I’m still capable of being judgmental, setting people up against myself, and projecting my own ugliness onto others, but it is a rare thing to find me stepping into such us vs them thinking. When it does occur I acknowledge it, take responsibility for it, and move on.
