In summary: white guilt attaches to all who are white, and only because they are white, not for anything they actually personally did. Even white immigrants to the USA from countries with no history of slavery or apartheid are still equally guilty because of their “whiteness”. And white guilt is forever, because black oppression is never diluted out to zero no matter how many generations intervene; there is always a residue.
So if I’m always guilty and you’re always my victim, forever, then why should I even bother about you? The condition is immutable. Go live your life and I’ll live mine. You’re on your own; best wishes and stop writing to me.
