“[born with] no preexisting moral guilt” — Is that some attempt to re-frame ignorance?
I have teenage kids and they sure as hell have been raised to understand, from a young age, that while they are in an unfairly advantaged group today, a few generations ago and they would have been rounded up, stripped of everything they worked hard for, and put in camps. And yet, even that fate was objectively better than other groups at the same time. What you call “moral guilt” I call empathy. Maybe this is simply what you mean by “virtue signaling”, but I want my kids to always look for those around them who are stumbling, unable to get back up, or who may just not have enough, and then to give help. But they won’t see them without empathy for those situations, and they won’t have that empathy without an understanding of the struggles.
