Can a White parent successfully raise Black children ?

I'm late to this but my wife and I adopted a white boy and neither of us is white. I don't think our experience has been drastically different from that of other transracial families, but I had another foster/adoptive mother (white) ask us how we ended up with a white child and then say that it "made sense" after she learned that he is Deaf. I felt like she was saying we weren't good enough for a "normal" white child but it "makes sense" because my son isn't good enough for a white family. Oh, and we had the opposite hair issues - my son has super curly hair that his bio family had no idea how to handle, so my wife and I taught him how to comb it and grow it out without it being wild
