Yes. Because racism is systemic and the effects build upon themselves. Which means that ADOS living in the US are experiencing the cumulative effects of 400+ years of oppression in the US. Redlining, blowing up or paving over thriving black communities just because of white jealousy, unequal lending, segregation, etc... those things happened here. Yes, atrocities have happened to black peoples all over the world - but there are certain nuances that only ADOS peoples experience here. Thus other black people from other places may not get all of the nuances and covert forms of racism that exist in the US.
Just like if I moved to the UK, there are probably certain racist terms I wouldn't understand or recognize because I didn't grow up there. I would have to be told and it still would not have the same visceral effect on me that it has on British black people. I wouldn't feel comfortable contradicting the experiences of a black brit and claiming their racist experience wasn't really that bad, etc.. but sometimes it feels like the same courtesy isn't returned when it's the experiences of ADOS.
I think of certain offensive terms like "gyp*ed" and how that made it into the American vernacular and was highly normalized. I didn't know the term was racist/xenophobic until I read an article about it later in life. A term I'd seen my whole life had been normalized with most people not even realizing it was offensive. Clearly various forms of racism and xenophobia hit differently depending on your proximity to them.
