Thanks for the link. I'm a white American who has been lucky enough to visit Sri Lanka! I don't agree with your conclusion that American racism is inescapable, or uniquely so. I believe we can make progress on bigotries - in particular, despite the current and despicable wave against people who are transgender, non-binary, or otherwise queer, I believe we have made significant progress in reducing homophobia over the last 5 decades (the ones I can remember!). On the negative side, I did reach the conclusion (due to what I've seen during the Trump era) that much of what I thought was progress on racism was simply racists learning to code-switch. That part's depressing.
