There’s no verbal insult that any black person can throw at a white person that stings as much as nigga or placing black in front of any expletive. Cracker, honky, gammon, Karen, whitey, red neck, they all carry no weight because they don’t diminish the recipient in the way that black bastard, black cunt, black fucker does. Or spic, greaser, spook. There’s not 400 years of subjugation or oppression or persecution or colonialism behind any of those terms, and they don’t define any of those who are being abused, because they have the privilege to carry on, and still get bank loans, still get mortgages, still get interviews for jobs as they are in a position of power because they are western and white.
Being called a Karen isn’t going to destabilise their life, cause them to question their worth, or make them wonder about their place in a society, where the majority of people look and think like they do.
Being called a black bastard because you disagree with some white person over who should get on a bus first, will make you question a lot of things..
