Why does Netflix portray Egyptians as black-skinned people, like portraying Cleopatra in her documentary series as dark-skinned? Isn't this racism towards Egyptians?

Netflix is just trying to be as much in tune with historical facts as possible and get some people out of the fairy tale that they have been immersed in for too many centuries. Cleopatra certainly has Greek ancestry, but her family had lived in Egypt for a few centuries already among a mainly “black” population at a time when racism was not systemic. The interbreeding of Cleopatra and a good part of her family is therefore logically inevitable and in terms of physical appearance Cleopatra is probably closer to Netflix's choice than Liz Taylor.

I inform you if you did not know that the ancient Egyptians were “black” and that immigration, wars, intermingling and miscegenation and also that certain discriminatory and oppressive policies of the conquerors of this territory were the main factors of the late change in the general aspect of Egyptian population as we see it today.

You also have to know that ***Kam/Cham/Ham are phonetic variants of Kem/Chem/Hem which constitutes the radical of "Kemet" and which also forms the root of the word "Chemistry". Hence the idea of ​​saying that "Km.t" would designate only the black soil of the Nile, and not the color of the skin, is really rubbish.
If the ancient Egyptians named people according to the appellation of the desert (Dšr.t), it should not be forgotten that the same term in ancient Egyptian language refer to the color "red" and that "red" is in many African cultures, and ancient ones outside the continent, the equivalent of the "white" or "fair" to designate the skin color/tone.

So there is nothing special if it happens that the banks of the Nile are rich in silt, but it is certainly not that, but the color of the skin, which explains the term used by the ancient Egyptians for to designate themselves as evidenced by the mythology of "Cham" when the latter is none other than the term "Kem" itself.***

Adele James, Netflix's Cleopatra actress >>>>
She could easily pass for the real sister of the little boy in the middle in the photo above. There are still among the Egyptian population some who have "white” skin, others who are more or less mixed like the Netflix actress and others who are more or less “black”. Don't you find your question a bit misplaced?

So the you are talking about is vis-à-vis which Egyptian?

There is no racism in establishing historical facts as they are and not as true racists and naive people would like to fantasize. I learned from the following very relevant post that an Egyptian lawyer has filed a lawsuit against Netflix:

Post deleted.
I sincerely advise the Egyptian Lawyer to rather sue historical artifacts, testimonies and authors, ancient Egyptian language and cultures, African continent, nature, God etc. and also vintage pics of everyday life in Egypte. They are the real culprits, Netflix has nothing to do with it.

One day people would have to come out of the fairy tale and willful ignorance into which racist ideology of past centuries had plunged them in such a disgusting way, right? They will see that reason has long been waiting for them at the door.
