My biggest problem with intersectionalism by the way, isn't so much the very concept of it, which is quite valid, but the fact that for whatever reason, almost all people who call themselves intersectionalist feminists care far more about stupid nonsense like this instead of actual serious issues that face women and minorities today.
Why was Black capitalized in that article and not others? Is that a thing now? I can't keep up anymore
I think I've finally gotten it, after long being confused and rejecting it out of hand: "Black with-a-capital-B" is supposed to refer to the specific and distinct culture of Black Americans, which, for a lack of a better phrase, share a common history in their descent from slaves. It does not include more recent immigrants (and their descendants), such as myself. I think. I've definitely seen "Black with-a-capital-B" used inclusive of the latter group, however, so I'm not entirely sure.
The fact that our language lacks a terminology for easily making such a distinction (at least one that doesn't require making overt reference to slavery, which seems grossly offensive) is a glaring omission.
