It’s not always 7 generations ago - there was a guy living here until a couple years back whose father was born in slavery - and it didn’t end instantly with the Civil War, or the demise of Jim Crow, or the Civil Rights movement — things like redlining ran into the 1970s and police violence and job discrimination never really stopped. White people can say it ended in the civil war era but there are plenty of people who know they still have to spend time thinking about risks their white peers do not.
