To give a few personal examples to try and reinforce the actual meaning of this thread:
When I worked in a retail job a few years ago, I was regularly ribbed by my white colleagues that my hair looked like pubic hair. If anybody ever flirted with me whilst I was serving at the till, I was genuinely told that this couldn't have been deliberate based on my hair. These comments were shrouded with laughter and in every single other way, these people genuinely enjoyed my company and respected my skills in the workplace. It seemed genuinely to be the case that they thought these remarks were funny.
I have a brother who is much younger than me, currently 19, and who is in all respects far, far more intelligent than I am. He has won scholarships to private schools and colleges and continues to excel in every way academically. We both have a black mother and a white father. He would come home, at 16 years old, and tell me fervently that black people have smaller brains and will never be as intelligent as white people. He showed me legitimate studies to support this, and became very upset with me that I would disagree with his 'facts'. He was actually proudly stating that he accepts he will never be as intelligent or capable as a white person and that we need to re-evaluate our opinions of ourselves to allow humanity to progress. He of course now does not believe this, but is especially angry that he was ever duped into believing it in the first place.
Despite all of this, the real fear and internal sickness started after I had my children, which is often the case for BAME people in the UK and the USA. As I watched a video made by the New York Times regarding George Floyd's death, I could picture my son in his position, and the anger that I had previously felt in my life was amplified to the point that I could barely coherently form a sentence without swearing. Suddenly everything else mattered in relation to this incident and became one ball of worry and disgust. So I am slowly trying to process this and explain how I feel, in the hope that some people will listen.
