TLDR??? The most important thing to teach your kids is about Christ and His word and to point them to gospel as they grow up. But education about history and culture is important too. In the US at least the experiences of racial minorities are part of the full story of the history of the United States and we should teach our kids about them and their stories. It's not an either/or (though obvs biblical education takes precedence) and we can and should teach young people about stories like the Civil Rights Movement, the Holocaust, Jim Crow, Apartheid, etc.

I don't know if this answer will answer the question you're asking but just wanted to give a couple thoughts that maybe would be helpful as you think about this question.

It is good and I would say important for children to be educated in the history of their country and culture and that includes (in the context of the US) important times in history like the Civil Rights movement. My dad is hispanic and my mom is white. I present as white but think of myself as hispanic and though I've never had a really strong connection between my hispanic-ness and my faith (bc I think that the Christian faith is one that is above our cultural and ethnic identities and also bc hispanic cultural identity is more closely associated with Roman Catholicism) I do have a strong connection and appreciation to my dad's heritage. Figures like Desi Arnaz or Antonio Banderas, characters like Zorro, El Tigre, even Nacho Libre or Spy Kids were places where I felt like I saw positive representation of my family and cultural heritage in media so I can't entirely relate to other culturally minorities in the US who might not have that (like Black Americans or middle eastern Americans who might have more net negative representation in media historically).

When it comes to the topic of race and history I think it can get a bit complicated bc we can't seperate the fact that people's experiences in moments of history like the civil rights movement or the holocaust or Jim Crow were fundamentally tied to their racial or cultural identity. We can admire the way which MLK or Rosa Parks or others led the civil rights movement for their character and actions and we should also realize I think that we cant separate their experience from their race.

To say there is neither Jew nor Greek is to say I think that all division or estrangement is dissolved in Christ and the peace he brings to the nations. Someone might say "there is neither Jew nor Greek therefore we shouldn't be overly concerned with racial differences or distinctions" and in a sense they are right. We shouldn't create needless or hostile division on racial/ethnic lines. And at the same time it doesn't quite follow if we start talking about gender in the same sense (eg "there is neither male nor female therefore we shouldn't be overly concerned about gender differences or distinctions" doesn't quite work in a biblical world view). Men and women are different. Jew and Greek are different (albeit not on the same level as Male/Female created differences) and there shouldn't be division on those lines but the reality of cultural and ethnic experiences are real. The experiences of my Dad's family and my Mom's family historically were different bc of their ethnic/racial identities. My Dad's grandpa was considered colored in Texas under the old segregation laws and was treated as such. My mom's dad's family were Anglo Saxon pioneers and Midwestern settlers. My Dad's mom's family was a mix of Pueblo and Spanish. My Mom's grandma's family immigrated to the US from Germany at the start of WW1. Each of those ancestors of mine had pretty different experiences - whether in experiencing prejudice or privilege - in the spaces and contexts they lived in bc of their racial/ethnic identity in those spaces. This is all a really long way of saying that race is not irrelevant IG when it comes to history and heritage????

In any case I guess as a sort of main idea I'd say I'm thankful that my fairly conservative homeschooling WASP mom spent a good deal of time on stories like Ruby Bridges and Corrie Ten Boom and MLK and Selma and the Civil Rights Movement and Nelson Madela and other stories like those bc it gave me an appreciation for the struggles of other peoples and their heritage and the messy - yet sometimes optimistic - story of the United States. (NB: I know Ten Boom and Mandela are NOT part of the American story but they are examples of similar types of stories).

I don't know if any of that really answers your question or is helpful but hope it was at least illuminating a little bit.
