Setting aside how stupid the general premise of thinking denying the existence of racism is doing Black people some huge favor, can we take a moment to appreciate how unintentionally ghoulish the phrase "I don't see skin" is? It sounds like they're trying to establish their Not Racist street cred by accidentally confusing Black people with Silent Hill monsters.
"When I look at another person, I don't see color. Or class. Or gender. Or age. Or height.
All I see is just another skinless, humanoid abomination from the pits of Hell that Satan forgot, cloaked in a translucent, skin-like membrane that unnaturally fluctuates in size and shape while screeching with a voice that sounds like the music heralding the death of God.
...that's the correct answer, right? Am I being a good ally?"
