My understanding and beliefs about racism were formed from a seminar I attended while in the USAF. They taught us that everyone has racist tendencies. Everyone. Anyone who tells you they do not are liars and are putting up a false front. The key to defeating the resident racism in your human nature is to acknowledge it and resolve to not succumb to it. I choose to treat my fellow humans with dignity and respect. When I hear people claim they have no racist tendences, I have to wonder what else they are hiding. They either do not know themselves very well, are in denial, or are simply lying.
Again. it is what you do, not your virtue signaling or attitudes that define who and what you are.
As a believer I repent and resolve before my Lord that I will crucify my flesh, I will die daily, and will be transformed by the renewal of my mind with His word. I choose to walk in love and in the Spirit.
I find dubious those who preach that they have no racist tendencies, are better than everyone else and use this as a weapon against the rest of us who acknowledge our nature, and strive to overcome it, while all they do is virtue signal, use this as a weapon, and judge others.
