Thanks for linking to that post and discussion. I almost replied to yours to say something about the relative obscurity of Juneteenth outside perhaps even specific parts of the US (having spent a fair time with Black American writing, I only found out about it because I found myself on a bus in Oakland during it in 2002), but didn't because I thought I was probably speaking too much from privilege. There's another set of questions there about the role of American discourse in discussions of oppression, too, about which my opinions are Profoundly Complicated. :)

(but FYI, I have a friend who teaches the history of the Civil Rights movement to her Scottish high school class, who did a good deal of American history when we were at university together in Scotland, but who has never lived in the US, and this week I taught her what Juneteenth is. I thought to ask because of this discussion! She's going to incorporate it into her classes so now a few more Scottish teenagers will know about it every year...)
