A few months ago, I read a book about the evolution of human behavior. In the section on why people are racist in the first place, the authors point out that human beings tend to dislike and mistrust people who are different than they are. They say that when different races marry and reproduce, it lessens the racism because now the person of a different race is part of their family. From that standpoint, I could see the truth in the quote. I agree with some of the other posters that racism couldn't have been the only reason he adopted a child.
