Why do different races and sexes discriminate against each other?

As I grow older and wiser, i interpret the information I am consuming and those that I have consumed in the past differently. My convinced conclusion solidified one thing, religion, history and other crucial information are severely infused with lies and distortions. I will not apologize to anyone or group or race but, I will welcome intellectual responses back and forth with civility. Empirically, there are humongous volume of hatred between races, ethnic groups, sexes and societies globally. These are not created by any supreme being but individuals or groups with one common goal.....stratify this sweet globe to make it up hill task for its inhabitants. If men are created in God's own image, why do we have taxonomical strata in every cardinal point of this beautiful world? Why do men treat women low? Why do white( I am quoting what is codified) treat black and coloured people(again, I am quoting from what is documented) low? Why do leaders of this world want certain region of the globe wiped out? The energy to keep this war going and to keep fighting this invisible but palpable war is exhausting and a causal agent for mental health conundrum and it is ubiquitous. Why do we classify ourselves? Are we in the animal sphere? Now, let us just refer to ourselves as fellow man and woman to end this human synthesized malady. Phenomenon of dominance and control is a full blown war on humanity, we need to deoxygenate it at once. Welcome to provocativedebate.com.
