@Esculent No one alive in the US may have experienced it (there are parts of the world where slavery still exists), but most likely everyone’s ancestors at some point had something to do with slavery. Until recent history, slavery was common all over the world. And no, that does not mean it was acceptable. I bet if it were possible to trace your ancestors back far enough, you’d find yourself related to someone who’d been enslaved. When we talk about slavery though, the focus is always on the enslavement of black people by white people in America. That’s only a small part of the big picture of slavery.
As for white history month, the whole idea just cracks me up. I think, “How would we celebrate that month? By giving more attention to the achievements of white people in classrooms or on TV?” And then I think, “Well that wouldn’t be out of the ordinary, so what’s the point?” Setting aside a month for a group of people doesn’t make sense when those people are in the majority.
