Karen is a pejorative term for a white woman perceived as entitled or demanding beyond the scope of what is normal.

You can downvote me as much as you want, but you need to learn to do research. If I say something is racist because I feel discriminated by you, then who are you to tell me how I should feel? Calling a white person a "wigger" doesn't change the fact that the origin of the w-word comes from the n-word. So using "Karen" for POC doesn't change the fact that it is STILL a racist term used towards White women.
