My inlaws are not happy people this last year. I hate to play armchair psychologist or whatever but it's like their relationship with the place is really brittle and disordered. Amber Frost had a quote somewhat recently about "joy" vs "glee". Times like these do not evoke joy, they evoke glee. Then they'll see an article that offers token criticism of civilian losses and despair like the cattle cars are coming.
I really don't like a lot of the rhetoric about cultural or racial intergenerational trauma... I think it stretches concepts like family systems and epigenetics to the limit of believability. It also poisoned by the dominant narrative. Zionists are often forgiven for being overly reactive because of intergenerational trauma, but somehow this is not applicable to Russians, for example. And really, all of us living are descended almost entirely from slaves and peasants. Even the oligarchy.
The "intergenerational trauma" in this case stretches back further than WWII into what basically constitutes ancient mythology. It is an evolved system to reconstitute and consolidate power within that system. The cultural narrative there is intentionally traumatizing, as such that there is a particular disordered response to these matters. It parallels a lot of the defense mechanisms you see in personality disordered people. Black/white thinking, shame vs guilt, extreme measures to avoid shame.
They will retell and retraumatize themselves the consequences of this genocide for generations without respect to what they perpetrated and the survivors of the genocide will have moved on and healed by then.
