Maybe if everyone stopped pretending they weren't descended from slaveowners, it would be less of a stigma and more of observing a fact about the world as it is? Everybody denying that they're descended from slaveholders just wipes slaveholders from history.
It becomes significantly harder to talk liberal/libertarian shit if everybody knows you're a descendant of slaveholders speaking to an audience of descendants of slaveholders, ridiculing the descendants of slaves.
