Karen: The anti-vaxxer soccer mom with speak-to-the-manager hair, explained

How the name “Karen” became an insult — and a meme. Feb 5, 2020, If your name is Karen, Becky, or Chad, you may have noticed a growing trend of people using your name as an insult. Increasingly, “Karen” in particular has emerged as the frontrunner for the average “basic white person name” — a pejorative catchall label for a wide range of behaviors thought to have connections to white privilege. Where a similar insult like “OK Boomer” stereotypes a specific generation, calling someone a “Karen” draws on associations people have built around extremely common names. But the stereotype the name conjures — at least in the US — is limited mainly to white women in their mid-30s or 40s. The archetypal “Karen” is blonde, has multiple young kids, and is usually an anti-vaxxer. Karen has a “can I speak to the manager” haircut and a controlling, superior attitude to go along with it: “It’s a little bit of a commentary on white privilege, perhaps.” … “Karen” isn’t alone in receiving this treatment. We’ve increasingly seen a lot of “basic white names” — commonly associated, rightly or wrongly, with Middle American white Protestants — being used in mocking memes that portray them as archetypes rather than individuals. … This trend might have also gotten a boost from social media, according to Dr. I.M. Nick, a nomenclature scholar and former president of the American Name Society.

Okay, well, it turns out that Dr. I.M. Nick really is an expert on names. She has recently published a book about names and Hitler.

But still …

Oxford Karen told me she’d seen the meme applied to other names like “Susan” and “Zach”— what she describes as “basic white people names.” … “From a scientific point of view, there is nothing intrinsic about a personal name that makes it ‘black’ or ‘white,’” Dr. Nick told me in an email. “What I think is brilliant about the Key & Peele sketch is that it underscores the fact that personal names are often used to help create and reinforce discriminatory and injurious power differentials within societies.”

Dr. Nick:

In other words, names have always played a key role in reinforcing existing societal rules, including power imbalances. The “Karen” meme, in fact, is part of a long tradition — and a pejorative one at that. Cleve Evans is a professor at Bellevue University in Nebraska who studies onomastics — the history and etymology of proper names. “There are myriad examples of words derived from names,” he told me in an email, including as racial or ethnic slurs. Names like “Paddy” and “Mick” functioned as anti-Irish slurs in the 19th century, while “Guido” was a common slur for Italians. Evans said the takeaway wasn’t that “Karen” is an insult now, but rather that names have always been fodder for this kind of use. “They are just another linguistic item that’s possible to be associated with a particular group because of the perception that it’s common among that group,” he said.

It’s almost as if it’s fashionable to racistly insult whites for being white these days.

Isn’t this all really sexist?

Sexist is still bad. Racist, it goes without saying, is good, as long as it’s anti-white racism.
