You explicitly endorsed teaching history by blaming a specific race.
Bullshit. The fact that redlining was done by people who were all (mostly? - not specified) of the same race, is not an indictment of all people of that race (or races). It is an indictment of those people. Not their progeny or their progeny's progeny. Painting it as such is merely an excuse for the revisionist history that is part and parcel of the New Republican Way.
I'm not even so concerned with the fact that redlining was mostly by a monoracial group, if indeed that's even so. What's critically important to understand is that was done
on the basis of race, intentionally and explicitly, and that this is one of several reasons why predominately white vs predominately black neighborhoods today live in artificial isolation from one another.
None of this could be discussed at all without triggering the Rhode Island law. Despite the fact that I think it is incredibly unlikely a high school kid would listen to this history and go "Wow, I feel
personally responsible for zoning laws that were voted in a decade before my parents were born, because I happen to have the same skin color as the city commissioner at the time!" Why would they? But they might, if they're smart or have a good teacher, go "Hang on a minute, is that why all of the shitty schools and crime are in the 'inner city', and all the nice stuff is out here, even though it's clear that this wasn't always the case? Is that why I, as a kid who grew up in
this neighborhood, never once had to worry about being a victim of a drive-by shooting while I walked to school unattended? Might there be a legitimate reason why people who do live in those neihgborhoods get angry sometimes at laws that seem aimed at persecuting those very neighborhoods and keeping them poor on the supposed basis of 'equal treatment' that was never actually all that equal because the dice was set for those kids forty years before either of us were born?"
And that's what Republicans are really afraid of, if by Republicans you mean the politicians who write laws like this. But you can't say that. So you paint a portrait of a mean evil Black Lady seminar-giver making innocent white children cry, and pretend that teaching history is what caused that, rather than acknowledging the role of history itself in building systems of mutual but unequal racial animus. And republicans, ie., the actual folks who vote in the politicians and post angry hurt things on social media, are easily convinced of this false narrative. Because they've never heard of Plessy v Ferguson, or redlining, or all the rest. Because unlike in Rhode Island, if you live in Detroit you don't need a law to prevent history teachers from teaching history, they'll vounteer. So
the first time they learn about any of this is when the smart man on the radio starts ranting about CRT and how devastating it is to the poor innocent white kids. Well, who wouldn't be outraged about that? Those mean old black people and self-hating bleeding heart liberals from Brown, why can't they just leave "us" alone!
