I think this is the more immediate question: do you agree with the claims that there have been a lot of racist acts in American history, that some of them continue today, and that even many of the past ones still have impacts today? Because there's a big difference between "I find this tiring that people keep talking about it, we already know" - in which case we should be talking about what we can do, instead - and "I disagree with these claims, but instead of trying to disprove them, I'm going to try to discredit them by complaining that I've heard it before." It sounds like the latter - questions like "how far back do things need to be" sounds like a disagreement that the effects continue. In which case: be straightforward! Just come out and disagree directly! Because the answer to a question like that is obviously situational, and depends on how much impact the sin had and continues to have.
