> (slang, originally African-American Vernacular, derogatory) A middle-aged white woman exhibiting a sense of entitlement or white privilege.
And if you are unclear what a racial slur is:

> An insult or slight, particularly one used to denigrate a specific group.
> “I’m not afraid of COVID-19 but what is scary, is the lack of common sense people have,” reads one of the most popular tweets about the coronavirus crisis. “I’m scared for people who actually need to go to the store & feed their fams but Susan and Karen stocked up for 30 years.”
This doesn't prove the point IMO. This word has been in the common vernacular for likely less than 2 years. It is not race based in my interpretation and also has evolved to mean someone who is entitled generally. You can choose to not be entitled but you can't choose to be not black or not gay.
I think this is reaching but apologies nonetheless.
> Karen is a pejorative slang term for an obnoxious, angry, entitled, and often racist middle-aged white woman who uses her privilege to get her way or police other people’s behaviors.
There are actual people with this name, and even if it was not racial, is it really okay to use pejoratives and denigrating terms, especially if that terms happen to be a quite common name in some parts of the world, like Denmark and Norway.
