I don't think they were wrong originally. If its caused by race, and not just awkwardness/incapability, then it is a racial micro-aggression. If you cross the street anytime you see a black person, but not an equally threatening white person, that's implicitly racist. If you won't make eye contact with a black person, but will for a white person, there's something in your brain telling you that it's wrong/bad, which is implicitly racist.
It's fine if you just struggle with eye contact. That isn't the thing at issue. It's if you won't make eye contact because of skin color. I feel like they should have issued a clarification, not saying it was wrong.
