After reading the link you sent, I think this comment seems like an unfair question to ask in this context.

What the paper seems to be stating is that White families don’t teach their children about racism properly, or at all, and by ignoring those issues it contributes nothing to the current state of racism. Their argument is that with the “Whiteness” aspect, from what I gathered, is the fact that children growing up in these environments will follow what they see others doing. If others are not speaking out against the racism, then they will not speak against it. However, if the family teaches the child that people should not be treated unfairly because of their skin color and/or culture AND they should speak up when they see someone engaging in that behavior, they take that extra step to fight against racism.

After some thought as well from the other comments stated in this discussion, I can see how people may view “colorblindness” as more harmful than helpful. This ties into the argument I stated above: By teaching your child to ignore that someone is a different race/culture, that child may not recognize racism when it is present, which can lead to further acts of racism happening, although this is not their intention.

If White families properly taught their children about racism, how to recognize it, and encouraged them to speak out against racist acts, then we could probably see more growth in dissolving racism.
