I know the dynamics are different, but I'm in reverse situation. White guy, brown wife.
One thing that I really didn't think hard enough about was when my mom told me she was "sad that her grandchildren wouldn't look like [her]" and I sorta blanked it out at the time because it was so fucked up. My wife definitely gets treated worse by my mother for internalized racism reasons among others. My mom is a big CNN lib and always pulls the "i have black friends/work with black people" card whenever I call her on saying something racist.
Ironically my total fox news addicted grandfather LOVES my wife. Partly i think because she reminds him a lot of my late grandmother in her personality. They got along the moment they met and he's treated her like she's part of the family since. He once tried to pull the "there's no more racism anymore" thing and I told him about some racist things that happened to my wife and he immediately paused and contemplated what he said and admitted to being wrong.
On my wifes side of the family, interracial marriages are super normal just due to the dynamics of the country and everyone is mixed 5 ways anyway.
