I just got up from conversation with a couple of older black men, that I said “well I got to go back to work and start cracking the whip.” And it occurred to me then that it was probably a really insensitive stupid thing to say.
Sadly, it hadn’t occurred to me until it’s already said.
Unfortunately, this keeps changing. Old slurs get recycled or forgotten, and new words become offensive. Corporate guidelines are often hugely overbroad to avoid offending anyone. The best way to avoid things like what just happened, by checking slang in a dictionary before using it.
