Saying "the first Black X" of anything reinforces an idea that Black (or diasporic African) history began when white people declared their inferior colony of Africans to be free.
Writers, poets, artists, dancers, athletes all existed prior. One of the greatest crimes of America (and the West) is its forced decoupling of a people and locking this colony (which is constantly being replenished and reformed) into a state of "newness", being felt to create anew because, like the British Museum, everything was taken and discarded because it had no value to settlers.
Happy #BlackHistoryMonth
