That's a total of 54 countries in what can't be much more than 30 years of adulthood (I'm assuming less than that, but let's go with the higher number for argument's sake).
The worldly perspective is good, but 54 countries in 30 years means a lot of time outside the U.S. Especially since you lived in four of those countries.
I'm aware of your overall themes in your writing. They're a fresh and useful perspective, but I don't really get the impression that writers on Medium look at the Black experience as a living hell. You'd have to ask them, of course, since the writers who offer the "anger" perspective are mostly Black writers. It's not appropriate for me to comment on Black anger, so I won't.
Living in Atlanta, I don't experience any Black anger at all. I'm treated with great courtesy in all my dealings , whether friends or Uber drivers or the plumber. So whatever you are seeing here on Medium is not seeping out into the real world as far as I can see.
I've spent a considerable amount of time working with folks who have been caught on the wrong side of the justice equation, of all ethnicities, and I wouldn't describe reaction to the Black experience with law enforcement as "fetishization".
Generally, it has been my experience that Black kids are treated more, shall we say, roughly, than whites, although that is changing somewhat because of the influx of Aryan nation types and meth/opioid heads from the white population. over the last several years. Those folks get pretty rough treatment, too. Once in the system, of course, everyone is left to fend for themselves, and you get centers of power among the various groups that get sorted out in various unpleasant ways.
The rough treatment handed down towards Black youth is handed down by Black law enforcement as much as white, sometimes even more so, because they're trying to "teach a lesson."
The reason I brought up location is that location outside the context of law enforcement and, instead, in the context of daily living, matters. Your experience in New York and even Florida stores (for example) will be different than it will be in areas of Georgia outside Atlanta, or in Alabama, or much of the rest of the South.
The elephant in the room still remains. There's a tremendous amount of ill will among people in my demographic towards the Black community. I hate that I have to say that, but I hear it plenty from white folks even here in Atlanta, who profile me as an older white guy and assume I'm on board with their malicious comments.
There is also a tremendous amount of support, too - but my discussion isn't about that.
When I correct these people, I get a wide variety of reactions, but none of them finish the discussion any more "schooled" than they were when it started.
In the end, the problems are always more nuanced than many writers and observers describe. That's what works so well with your writing - you pull out those nuances and highlight them with regularity, so if I bother to comment, it's going to be offer another perspective.
