For all the people saying MLK's speech doesn't reflect the sentiment of "not seeing someone's skin colour," I think that is exactly what he was dreaming of - a world where it just is irrelevant to how we treat one another. It should be of no more significance than the colour of a person's eyes.
Robin Di Angelo is a white woman who has made a fortune out of telling other white people that they are racist. She says that in any interaction with a poc, a white person should constantly be focusing on their race. She talks and writes about how she finds black women scary and she describes herself as racist - and she has made a career out of assuming that every white person is as racist as she is.
Her ideas have unfortunately become quite widespread and many on this thread are espousing them, in some cases clearly not recognising their provenance. She is one who says you have to be "anti racist" by which she means that you should keep race uppermost in your mind at all times, and consider it to be the most important part of any person you interact with.
It couldn't be further away from the dream that we will be judged by our character and not the colour of our skin.
