I'm also in Tulsa (small world, considering the size of Lemmy). While it's not a financial and cultural hub like it was, it's finally getting better over the last 5ish years.
If anyone's interested, there's a 501c3 called Justice for Greenwood that seeks reparations to help rebuild the area. There was a court case but it got dismissed (can't recall details atm). https://www.justiceforgreenwood.org/
Grew up in Tulsa, I only learned about it from my mom (not public school) because she did a paper on the "Tulsa Race Riots" in college in the 80s.
