The current strategy by the carefully staged and optics savvy Meghan and Harry was Meghan's sound-bite about racism being different from rudeness, when comparing the Press treatment of Kate with the treatment of Meghan. No doubt they will run with that because a
lot of people like to jump on the racism bandwagon in the context of BLM. I think BLM is about real issues of harsher treatment by police and the judicial system, lack of opportunity to reasonably good schools, reasonably good homes in areas not populated by violent gangs of drug-dealers seeking to recruit children or drug-addicts robbing you for their next fix, access to opportunities to use your potential and skills to build a safe and secure life for yourself and your loved ones, access to healthcare etc. None of this applies to Meghan and her trust-fund husband.
As far as I am concerned racism is just one form of rudeness. I totally reject the idea of exceptionalism people try to attach to racism because of white people being exceptionally good at the slave trade due to industrialising first thanks to the presence of huge amounts of coal deposits that could be mined, the sense of innovation brought about by historical events etc . If dark people in that era had had been exposed to similar events and circumstances and had the opportunity, they would have behaved in the same way as white people - increased melanin production in hotter climates does not cause a person to be more compassionate or kind (just have to look at the caste system to see that). An industrialised 'darkie' nation would have been equally ruthless in their pursuit of slavery - they were after all engaging in slavery themselves and were also the people capturing slaves to sell to white people.
I think expressing racism is just being rude. If we were kind and thoughtful we would not express racism. I reject Meghan's assertions trying to create a distinction based on race about the Press treatment of her compared to the Press rudeness to Kate. Some people - white and dark - are racist of course so no doubt there was some racism expressed by some people,, which is as rude as misogyny faced by Kate or misandry faced by Charles for not being the 'man' his father wanted him to be - or any of those other -ism terms.
