That was really unfortunate. However, I doubt that happened with malicious intent.
While I agree that the absolute likelihood of malicious intent may not have been meant by the person in question... or not...
This is the dark side of institutional racism.
Why do some white folk cross the street when they see a black man walking down their side of the sidewalk? Why did my parents tell me to lock the car door when we drove into North St. Louis where the Symphony Hall is? ("Our own little Beirut" as I've heard it called a few times).
It's our subtle programming as white folk, or even non-blacks. I know a few too many Mexicans that make some of the average white racists I've known look like freakin' angels!
Anyway.
Point is, it's not the meaning behind it. It's that it is all too common of an occurrence for half the population. And it's not just a momentary slight, rather a lifelong assault.
My Wife, her Brother... their Father... They've all experienced it.
I walked away from my racist friends when I left high school and spent a good long time trying to undue that systemic, subconscious damage done to me growing up in white bread suburbia. And the unique thing was my high school was tipping from majority white to majority black while I was there. This made the programming much more subversive and insidious!
I was guilty of going along with it for too long. Hell, even one year is too long to be "OK".
I'd like to think I'm better now, some 29 years later.
To be fair... there are many other words than "monkey" to clarify "M" over a radio.
