So it's actually a pretty interesting read but I think this paragraph gets the idea across pretty well:

(Obv out of context)

Most current antisemitism in Eastern Europe is closely related to these debates, as nationalists strive to “fix” their nations’ collaboration (or in the case of the Baltics and Ukraine, participation) in the Holocaust with revised paradigms that equal everything out. One of the poisons of ultranationalism is the perceived need to construct a perfect history (no country on the planet has one of those). Another is hatred of local Jewish communities who have memory, or family, or collective memory, of nationalist neighbors turning viciously on their neighbors in 1941, and of the Soviets being responsible for their own grandparents or parents being saved from the Holocaust. In America, this would be akin to someone hating African Americans for having a different opinion of Washington or Jefferson because they were slaveholders.
