Thank you for sharing this!
Beautiful harmonies, and it faithfully recreating the style and feel of the old U.S.A.,
but then deliver its very poignant modern message. It is is bitter to acknowledge
that even in that rapturous sunglow recalling of the early days of the U.S.,
it was still a colonial project, that would be ravaging the Americas
for a long time before achieving its present, very imperfect
degree of integration, and repairing some of the harm
that can yet be repaired.

Still, it's true that the descendants of the original migrants
have no moral right to kick down the ladder like that.

There is a morbid joke told around here that runs along the same lines:

A couple of siblings from the Caucasus, the Southern region of Russia,
arrive in Moscow as ask a policeman what do they need to do
to become Russian citizens. The cop points to the red star
on top of Spasskaya Tower of Kremlin,
and says that whoever climbs up there and kisses the star
would become a true Russian. The brothers climb up the tower,
and one of them reaches the top and kisses the star first.
His sibling is struggling to climb up the last ledge, and cries out,
"Help me, brother!" The first sibling sneers, "You're no brother of mine, (racial slur)!"
and kicks the other sibling down, showing that, along with his status as a true Russian,
he has absorbed the bigotry towards migrants that the "core" Russians are notorious for.

The harmonies are indeed stunning.

And wow, that's quite the story, and clearly applicable worldwide to this day.

Plus ça change, plus c'est la même chose.

I'd say that you shouldn't have shied away from including the slur there.

The more things change, the more they stay the same, indeed. There is some hope and progress, though.

The slur is awkward when translated, literally "black-ass nit",
as the migrants from Southern regions (Chechnya and Dagestan)
and neighboring countries (Armenia, Georgia, Azerbaijan) are called "blacks" by the Russian racists,
even though many people from those regions would be considered rather pale by anyone from the nearby Levant.
There are also a separate racial slur for the migrants from Central Asia,
and from many other places. Russia had had its own Manifest Destiny march
across all the territories it now incorporates, and this imperialist arrogance
is still strong in many people, as evidence by the ongoing war.

Much as the US has developed slurs for each new wave of immigrants.

It's a list too long to enumerate here.

And that slur is pretty clear.

Yeah, all hate speech is easily recognizable
by its focus on dehumanizing the person,
comparing them to insects, germs, disease, filth.

Chivington at Sand Creek: "We must kill them big and little. Nits make lice."

But there is some linguistic nuance there,
the same way "an asshole" is not a literal rectum, but a bad person,
and in the same way the "nit" part of the slur is also used
as a general swearword for scummy individuals.

It is ever thus.
