I remember Boozer yelling "yeah boy" or "get that out of here boy" after an AK47 block. Did anyone back then think of it as a racial slur? I guess you have to be a super SJW these days to know all the terms.
I think you have to be staggeringly uninformed to be unaware how offensive it is to use address a black person as "boy", and deliberately obstructionary to pretend to not know the difference between calling someone "Boy" and a phrase such as "Yeah boy!".
By the way, for those who are staggeringly uninformed, I would not refer to an elderly black person as "uncle" or "auntie" unless you know them intimately, preferably with an actual blood/marriage relationship.
