Well. If we are being politically correct, a black guy marrying a white chick and the being duped and lied to by a white guy such that he murders his wife in a fit of rage probably should not be shown. Too demeaning of the black guy
Othello wasn’t even black. He was supposed to be a Moor, a North African. North Africans, although darker than Europeans, are still Caucasian, not sub-Saharan black.
