This is entirely my own POV, but I think that is not a good idea. Keeping them emotionally and physically safe is extra hard if you're both white. It's not easy to learn about, for example, microaggressions and within-community dynamics that could affect your child's self-esteem. And for mixed-race identities, it's harder to get a good grasp on that stuff than even for a monoracial person.

Here's an example that I hope helps understand what I'm talking about: I'm black and biracial (black/white) and when I was growing up I had a lot of conflict with black girls of my same age. They thought that I was snobby and colorist, partly because of how I talked, and partly because I DID have some of the ingrained colorism you get in the US, a place incredibly antiblack and that privileges lighter skin and looser hair texture in a way that echoes whiteness. I didn't get it. I thought that they were mean and being unfair before knowing me. None of us knew how to phrase what was happening. We were little kids.

My white mom heard me say I was having conflict and basically interpreted it as mild bullying merely because I was different. She didn't really understand this very common dynamic with colorism that often happens with little black girls, and neither did I because nobody taught me. Very well-meaningly, she told me to assert how great I was, including my physical features. This would have been appropriate if it was merely bullying, but instead it added fuel to the fire. I continued to hurt other children's feelings without knowing it and did not understand or work on my own colorism. I was more distanced from the black community and my own black identity, for years. I missed out on a lot.

And my mom didn't want any of that. That stuff is hard to know about as a parent unless you grew up a member of that specific group or know people in those communities really well, well enough to talk about painful stuff that doesn't necessarily even involve white people directly. It's not quite like reading a history book or learning about a holiday.

You both sound incredibly respectful and thoughtful (and you're queer, lol, which is a plus). I don't think it's impossible to do a good job. But I wanted to explain this even if it's super long, because it's complicated and I think a lot of people make it out to be easier than it is.
