No, I'd disown them. And I'm pretty sure that almost everyone secretly finds interracial relationships to be weird and offensive, they've just been brainwashed and browbeaten into pretending that it's perfectly fine.
My White older brother married a girl from Hong Kong that he met at UC Berkeley, and it pisses me off every time that I think about it or when I see his wife and his weird looking hapa kids even though I'm friendly and smiling on the outside when I'm around them. And White/East Asian interracial relationships are probably the least offensive interracial pairings since both Whites and East Asians have high IQs and civilized genes.
Engaging in miscegenation with blacks will have a dysgenic effect on our race and is equivalent to beastiality in my mind. You might as well be having sex with a gorilla. Why would you want to give your offspring an inferior brain and hideous phenotypical features? I can sort of understand why liberal "anti-racists" would want to be in a relationship with a black person in order to make a political statement, but genuine attraction? Their skin tone, hair texture, facial structure, and behavior is just so unappealing. Fuck liberal street cred; you could never convince me to find a black woman attractive even when I was borderline Antifa.
