@4 Unless they are part of one. People I know whose parents are of different races have run into all sorts of bigotry from adults. People not accepting that they are parent and child, people assuming that a parent is a nanny. Lots of being told that your family doesn't make sense or isn't a normal family. But, hopefully, as time progresses those assumptions will die out, and then kids will not be getting as much bigotry from older generations. It's certainly a good sign that the kids growing up now will be less likely to do that to the children of the future.
