it really depends on how they're raised, and what/which culture they are taught under, which usually comes down to who their father is, though the mother's heritage/culture will always play a part. What I mean by that, is most mixed kids that are begotten from black fathers likely grow up WITHOUT a father period (as is the unfortunate case with most black kids too), if you know what I mean, which -- mixed or not will always cause identity issues as opposed to white fathers, typically being more present protectors/providers, trying to maintain a stable family unit.
I would say mixed kids are generally okay or even good if the father is white and continues to imprint his culture onto his kids, its just not ideal if the father is non white (I wouldn't go as far as to denigrate genuine mixed kids from non-white fathers as "mystery mullato mutts" or "mudshark goblinos"), which is kinda the point of bleached, and a western tradition of colonisation. Again some right wing people especially hardcore race realist alt-right neo nazi types will always point out how degenerate it is period and have all these highly specific examples of mixed psychopathic incel examples as a warning against like yellow fever or what have you "muh eliot rogers", but there's no shortage of pure kids (white or non-white) being just as psychopathic or problematic under poor living conditions/raised incorrectly. There's also lots of examples of well to do mixed individuals that I would deem as a net positive on the world.
My entire view on this is simply don't do it out of some kind of kink or fetish, and especially not out of Jewish advertisement propaganda lol (you see the billboards and ads and mixed couples in tv series everywhere), I'd say do it only out of genuine love as you would with anyone else, because I would still caution against blanket race mixing and miscegenation. I have no issues with a very small minority of mixed people under a monoculture (ideally a western culture), its the multiculturalism that's the problem, because it simply doesn't lead to good outcomes for society. Subcultures that emerge from some cases are 'fine' but again imagine the real identity issues if say, a white catholic raised man marries an arabic muslim raised woman and the children are taught contradictory religious and societal values under both parents, one of the parents has to win out and it's usually the father. So I guess whatever you do, make sure you be a good father.
