Uh, I know nothing about Rosenbaum's ancestry or history other than that he is Jewish, which Mary Anne mentioned, so this is not a comment about him, but there are people from Mediterranean Europe (southern Italy etc.) whose skin is as dark or darker than mine but in current US terminology--and Mary Anne grew up in the US--that doesn't make them POC/non-white/racial minorities.

This story feels in some way as though it is touching on the question of whether Jews in America are considered white (answer, as far as I can tell: ". . . that's complicated"), but I am not about to defend definitions based strictly on skin color or the ways in which ethnicities are read by outsiders, because ack; that is just where my brain went on seeing a story about a Jewish writer being invited into a POC-only space.
