It's not the teaching of the skill in itself that is problematic, or even (in my opinion) the attempt to make up for various sources of disadvantage.
What I object to is the idea that it is of great importance to eliminate racial and gender disparities, or that our society is incredibly bad because these disparities exist. This idea is what drives articles like this to the front page of HN.
Racial and gender disparities exist for a number of reasons, not simply the oppression of one group by another. Different groups have different cultures, interests and possibly innate abilities. I don't think anyone here would want to instantly eliminate the cultural differences between Black and White people.
The claim that the differences between groups are solely attributable to disadvantage and oppression is simply a claim. It is backed up by nothing but moralizing and posturing (note the number of posts here disparaging White "kids").
I also don't think that it is possible to entirely eliminate the disadvantage that minority groups often suffer, simply because people by nature tend to favor people who are similar to themselves, by any measure. I certainly wouldn't consider it wise to go to a random country, say Israel, and mandate that all cultures and viewpoints were to have equal status in that country, and that the majority would have to give up on all aspects of their culture that were not sufficiently inclusive or friendly to minorities.
