I don’t think you should be telling others to “get a grip,” because their experience differs from your own, but here we are. Perhaps don’t make such obnoxious assumptions if you don’t want to be treated that way in kind.

I’m also skeptical of the extent of your actual experience if you think this behavior is “out of line” in American society. It was quite routine in mine. The first time I saw someone throw food at the head of a cashier I was shocked, but quite quickly became inured.

You tried to attached the American cultural norm of manners and courtesy to their history of black slavery.

"Get a grip" is a pretty mild response to something so absurd, hyperbolic, and flat out insulting.

No, I tied our history of slavery to the widespread abuse of service workers, and working class people more generally. This is not in anyway hyperbolic. Go read W.E. Dubois on wage labor. Or look at the distribution of service vs. professional-class jobs among minorities prior to and after the Civil Rights Movement. I likewise witnessed plenty of anti-black racism directed at my coworkers in these settings, both from customers and management. But that has no prior context in American history and was invented solely in the wickedness of individual hearts. Sure, okay.
