If we all agree that a people can experience trauma on a large scale and that trauma can then pass onto the descendants, then the reverse must also be true – a people who have inflicted trauma on a large scale pass that experience onto the descendants.
People who are descended from people from slave-owning and imperialist nations carry with them the scars of slave ownership, genocide, oppression. It shows in the way they act, speak, think. Their worldview is informed by their history as masters of “lesser people”.
I think this is a false equivalence. Trauma is a…(sorry, im not a mental health expert) primal thing(?). As in, trauma is a part of your flight/fight/freeze/fawn response. The things that cause fear and despair and such that impact your survival can be passed down to your offspring to help them survive. But superiority and racism are something that’s taught. There is a somewhat basic impulse (possibly) to be secure and to be wary of other “tribes” but it’s not something passed down into offspring’s subconscious, but something taught at a higher level.
I don’t think we should forget that the woman who avenged Che Guevara was the daughter of a nazi
