Will Christopher Barclay make good my request, I wonder, or will he be content with having merely cast his racist “white man” aspersion?

“I’m not sure what point Rehat1 is making here.”
A certain tribe is evil. It is behind every single intrigue, war and destabilization currently under way anywhere in the world, exactly as it explains everything bad that has ever happened in the past.
You now know the only thing you need to know to understand absolutely everything: one tribe, one world, one conspiracy.

Do explain the difference between a “white” man and a “black” man to me. I mean, the “essential” difference between the two.

I’m not sure what point Rehat1 is making here. The fact that Ukraine was widely involved in the murder of Jews was well known and dated back to the 19thC. Perhaps the most telling account is that of the Police Chief of Odessa boasting he had himself killed thousands of a Jews as they fled the city naked and on foot in 1941. Tens of thousands were killed. The area was at the time under the occupation of Romanian forces and according to some it was on the insistence of the King and the Catholic Church that the police chief and colleagues were arrested for mass murder and imprisoned in Romania for some months. The Romanian authorities forbade anti Jewish programs. The police were later released after German pressure. It is also well known that killing of Jews in places like Lviv started in 1941 before the German Army even arrived! 30,000 Jews were massacred on that single occasion. Ukrainian Auxiliary police largely manned the Extermination Camps in Poland. The large scale of killing of Poles especially in Western Ukraine goes unremarked on today, it no doubt being a “sensitive” subject. Ukrainian Nationalists were still fighting a terrorist war against the Red Army in the 1950’s although many ended up in Canada and the US where their descendants are important politically and as can be imagined were delighted by the 2014 Kiev coup and had helped fund the Maiden “protesters”. Is it now argued Ukraine isn’t deeply anti Semitic? Phillipe Sands book East West Street gives fascinating insight into some of these events.

Thanks, white man, for editing brother Baraka’s article. Now you’ve put him in his place, I’m sure, he’ll be a good boy and submit his next article to be corrected by you before publication.

An inevitable consequence of identity politics based on ethnicity was that racist whites would say, “We’ll have some of that”.
Also worth noting is what is happening on many US campuses especially Evergreen University, where African-Americans are attempting to re-introduce formal segregation on the basis of race.

The white supremacy that some of us see as more insidious is not reflected in the simple, stereotypical images of the angry, Nazi-saluting alt-righter or even Donald Trump. Instead, it is the normalized and thus invisible white supremacist ideology inculcated into cultural and educational institutions and the policies that stem from those ideas.

Rather, to break free of the racial paradigm in order to decisively shift the narrative and come a bit closer to a better approximation to the truth, what Baraka should have written is something like this:

The [ideological] supremacy that some of us see as more insidious is not [accurately] reflected in the simple, stereotypical images of the angry, [white supremacist] Nazi-saluting alt-righter or even Donald Trump. Instead, it is the normalized and thus invisible [fascistic] supremacist ideology [unconsciously] inculcated into cultural and educational institutions and the policies that stem from those ideas.

In that fashion, I would amend the whole of Baraka’s piece.
Capitalism doesn’t have or even favor a color but for purely contingent historical factors, although in its fascistic phase, in periods of crisis, of potential or actual mass rebellions, it may indeed (and does) opportunistically foment divisions along the lines of existing popular racial prejudices, as along the lines of any number of other culturally reified (or ontologized) ethnic “differences.”
Other than that, Baraka’s piece is well worth the read and mulling over . . .
