Keep spouting your BS until your red in the face, racism isn't an inbuilt thing, people aren't born racists... your FOS.
People are born to be more suspicious and less trusting of people different to them. Whether that be skin colour, race, religion ect. Even people who have never consciously said or done a racist thing in their life have in built subconscious bias, which has been scientifically tested.
I suggest you do some reading on just how much your subconscious thoughts and biases control your decisions in your life. I wonder if you were really put under the microscope would you treat every person from every race and religion exactly the same...? Hmm... A muslim man with a thick beard and a ticking backpack sits next to you on the train. Would your heart rate be EXACTLY the same if that man was now a 70 year old white grandma with the backpack? I wonder...
Maybe you are the only completely pure person on this earth? Maybe you have evolved far beyond anyone else...
The point is stop pretending that we are going to "end" racism. We need to understand how to deal with it a lot better because these public headlines are not the answer...
