I know this comes dangerously close to the cuckservative "liberals are the real racists!!11" line but there's some truth to it.
And obviously you see it from "the right" as well, Crowder et all. "Blacks dindu nuffin, it's just those mean old antifa ruining their message!" The infantilization of black people--the idea that they don't really have agency in the same was as whites--is sort of part of our creation myth as a nation.
And maybe there's too much truth to that idea for us to really get past it as a culture.
Most of the powers that be don't want anyone to "get past it" or "work it out" it's a tool to be wielded by the media and such, to point the mindless mob where to go.
