Well, one can hope otherwise – my grandfather was pretty racist, like Archie Bunker except born and bred in the South (Nashville to be precise). Over the years he really mellowed out, not just about race but in general. At one point his church hired an African American pastor, and if there was any one specific milestone that changed his thinking, I’m wondering if that might have been it. (This was all before he met my wife, who’s Ethiopian.)
I’m astounded by how reactionary a lot of people I went to high school with have become. (Really, just astounded that it’s non-zero.)
