The opposite is also true: "Absent significant study, it is absolutely not the place of someone who is a member of the racial minority to declare the extent or impact of racism." Why not say simply it is not the place of someone to declare the extent or impact of racism without study?
Also I believe you are assuming the race of the parent. For all you know they could be a member of a racial minority.
More to the point what is our goal WRT racism? To eliminate associating traits with a person purely based on their race that are not backed up by a correlation? If that's the case affirmative actively works against that goal.
