Spreading the anti-white message. Why was it necessary to call the white family racist? If the roles were reversed and a black family made the same comment about two majority-white countries, no one would blink an eye. Not an accurate representation of an average white family in America and this message of "it's not ok to be white" is not ok.
Also, if a white family wanted their child to only be with a white person it would be racist, but it's ok when other races/ethnicities want to date within their own group? Make it make sense.
