The OP is fully aware that Karens and Kens refer to white people.
You argue impulsively. Did you bother to look up the origin of Karen before you asked someone to prove you wrong
https://en.wikipedia.org/wiki/Karen_(slang)
Karen is a pejorative term for a white woman perceived as entitled or demanding beyond the scope of what is normal. The term is often portrayed in memes depicting white women who use their privilege to demand their own way.[1][2] Depictions may include demanding to "speak to the manager", being racist, such as calling the police on black people simply because of their race, or sporting a particular bob cut hairstyle.[3] A notable example was the Central Park birdwatching incident.
The term has been criticized as being ageist, sexist, racist, classist, misogynistic and seeking to control women's behavior.[3] As of 2020, the term increasingly appeared in media and social media as a general-purpose criticism of middle class white women, especially during the COVID-19 pandemic and Black Lives Matter protests.[1] The term has also been applied to certain male behavior.[3][4] The Guardian called 2020 "the year of Karen".[5]
Origin
In African-American culture, there is a long history of calling meddlesome white women by a certain name. In the antebellum era (1815–1861), "Miss Ann" was used.[6] In the early 1990s, "Becky" was used.[7] As late as 2018, before the use of "Karen" caught on, alliterative names matching particular incidents were used, such as "Barbecue Becky", "Cornerstore Caroline", and "Permit Patty".[8]
