Many times the Torah talks about Nations as if they are races. Just as we talk about the different races of dogs. A Labrador is forever very friendly and happy to help. A Rottweiler is always strong, fearless and aloof.
Similarly, some Peoples are not allowed to convert to Judaism because of their horrendous character traits; some only after three generations.
Nations were often named after a geographical site or forefather but also frequently after their language (the Hebrews).
The prominence of language makes sense as that may determine how we think, what we are aware of and what our character traits could be.
So, all-in-all, the Holiest of Jewish Scripture seems through-and-through racist. However.
Maimonides tell us, based on the Talmud (Yoma 54a), that Sennacherib, King of Assyria, mixed and exiled all the nations he conquered to confuse their identities as to discourage them from rebelling.
From this, our Sages conclude that we can’t anymore tell one People from another in the original sense. Therefore, luckily and (I believe) deliberately, none of the national stigmas in the holy Torah can be applied.
This way, G^d shows that racism is nonsense and takes the wind out of racists’ sails if they wanted to point out differences between groups of people. We still have more in common that what divides us.
But in any case, for Jewish Law, there are only two kinds of Nations: Jews and Gentiles. And this is not racism either since anyone who wants to become and is capable of becoming a Jew is allowed to convert. This shows that Jews aren’t a race but rather a Nation — with a special calling.
That the wife of Moses is called Black (Kushit) (Numbers 12:1) is not referring to her skin color. Kush is the name of her Nation, Ethiopia.
And easily, she could have been not from Kush (per Exodus 2:16-21, she was a Midianite) but rather was having the piety as women from there. She wouldn’t say her piece about her own issues and then Miriam felt compelled to speak up for her sister-in-law — perhaps.
This all has nothing to do with Europeans 400 years ago, downgrading Africans to animals to feel free to hunt, sell, abuse, rape and kill them. Or with White people being obsessed with skin color.
Not one negative thing is shared about Moses’ wife. She is also not exotified. So, how could this be racism? Heaven forbid. And assuming that Moses himself must have been White is racist to begin with.
If already the Jewish tradition has anything to say about black then it’s that black is beautiful. In the Hymn Annim Zemirot (Shabbat morning, Ashkenazic) we sing that G^d must have [gorgeous] black curls! And Rashi says that Tzipporah’s blackness meant that she was beautiful.
So, no, the Torah and Judaism are not racist. The rabbis clarify that we received the story of Adam and Eve to teach us that we all come from the same parents. No one needs to put on any airs about our origin.
Just what modern science tells us. NB: Whites are an adaptation to climates with little sun to still get enough Vitamin D. The detriments are big. Brittle hair hanging for your eyes, easier skin burns and skin cancer.
Let me end by quoting – from memory – a poem that a teenager about 45 years ago sent to the leftwing VPRO gids, a Dutch TV guide (whodonit).
When you feel good, you are pink.
When you are cold, you are blue.
When you are angry, you are red.
When you are sick, you are yellow.
When you are dead, you are white.
When I feel good, I am brown.
When I am cold, I am brown.
When I am angry, I am brown.
When I am sick, I am brown.
When I am dead, I am brown.
And they call me a person of color.
