Yea you could use it to show them the one drop rule and how white supremacists wrote into law to consider anybody black if they have a single drop of black blood and how that shaped our societal perceptions.
Or, like other people have figured out in that thread obviously cus black people are racist against white people.
If it wouldn't surprise you why was your first instinct to call this false and defend Twitter with an argument like "that wouldnt make sense"?
You see how your obsession with giving fascists the benefit of the doubt just helps them?
