Racism is discrimination of a different race based on the belief that your own race is superior. Systemic racism doesn't exist in the United States. There are racists in the United States, but that doesn't mean institutions are inherently racist. Also, racial stereotyping isn't necessarily based on racism and not all bigots are racists. You can make an argument for systemic discrimination, but not on racial superiority.

You are right, but many feel that casting all into overly broad categories of privilege does invalidate their personal experience whether that was the intended aim or not

made up words like "systemic racism" doesn't make those terms real.

Nor does a party voting for Biden and Harris - creators of "systemically racist" laws and corrupt DAs that used those laws to jail innocent black men - have any moral position to talk about such made up words and expect to be taken seriously.
