I was also agreeing with the GP. The author of the article is the one exhibiting white supremacist behavior by mentioning it in the article when it's unnecessary.
Lacing white supremacy with sentiments of guilt or condemnation doesn't make it any less an example of white supremacy. Perhaps the least interesting thing about the people who went to the moon is the color of their skin. Only racists care what color their skin was. Old school white supremacists say it's great that they were white, new school white supremacists are upset that the whites did so well (are/were supreme). Both are racist, and we'd be better off moving past them.
