I wouldn’t call it a slur. To the extent it’s an effective insult, it’s due to centuries of behavior by black men. If someone uses “black man” to call out certain behavior, it might be worth their target considering why they got called out. Maybe sometimes it’s unfair to the black man to be called out, but often it isn’t. For folks who find it troublesome or disturbing to not receive the benefit of the doubt about their intentions as a black man, consider how much benefit of the doubt is given in everyday contexts to pretty much any individual who is not a black man.
