But it does serve as a reminder that when people want others to feel guilt to very, very carefully consider whether and how much guilt to actually place. Guilt is a terribly powerful emotion (whole religions run off it-“original sin”) and shouldn’t be wielded too broadly and too irredeemably. It probably shouldn’t be held against people’s kids/family/friends except in very important scenarios (like organized crime), for instance. It probably shouldn’t become something like a prejudicial “scarlet letter” too easily. Etc. and people should generally be given a way back to society and not discarded as trash. (Which maybe that’s what “original sin” does for those religions in a way?)
If the next generation ought feel zero guilt about the past, then the right way to do this is to relegate racial history to graduate studies or strike it from history altogether. Historical atrocities are a serious affront to national pride. Part of why Shinzo Abe was so controversial was because he wanted to strike some matters from history; this is a thing at least because of a shared acute sense of pain that results from this knowledge.
I think this is also part of why race in school curriculum is such a big deal right now in conservative politics. The magnitude of "white guilt" surely cannot be because Democrats are talking about it on CNN; it's because every child learns about it in school. There's no cure for this pain quite like not knowing at all.
The dogma is more about being compassionate for others and recognizing that they may have had more struggles than you and they certainly have had their own life that has led them to where they are.
The times that I have seen this dogma well-enacted it's been about listening to people, and it has not been limited to recognizing this only for people of different races/creeds/colors, but also for people who are acting in a racist way. It's definitely very hard to navigate well, but it has been convincingly correct to me when I saw it happen.
