Here's my two cent counter-argument. Captialism is the biggest ruthless killing machine, whatever form it takes: nazism (Hitler was put to power by German industry/bourgeoisie), fascism (Mussolini advocated for State/Capital unification under "corporatism"), State capitalism (USSR was not
very different from a people's perspective, with salaried work and gulags and political police), or ordinary liberalism (French republic orchestrated the colonization and slavery of many folks, even long after slavery was formally abolished, under the form of wage slavery).
Yet there's little memory of those massacres and injustices, except for casualties of war who get the whole triumphant nationalist ceremonies to spit on them. Maybe a plaque for the dead workers who built a mountain road/rail, or for the victims of the Commune of Paris/Lyon/wherever. It's very discreet, when it exists at all, when it doesn't fall into the narrative of the State.
I don't know about younger folks, but when i was in school we got told so little about the history and reasons for these people to have died, when talking about it at all (good luck finding a history teacher spending more than 1 hour on the Paris Commune or the Algerian independence War). And we got told exactly zero about the living popular history of our own neighborhood and how people defied those injustices.
Whenever i find a plaque, memorial, carving or whatever remembering the past (and its mistakes) i try to take some time to investigate it, and i often learn something interesting. So much happened right around us, yet we are told/taught so little, and in the cities urban renovation driven by gentrifiers makes sure this history stays hidden and that only advertisement and store fronts remain.
Is that really the environment we want: an efficient, emotionless and pastless business machine? I personally don't want that. I wouldn't go so far as to call you a NIMBY resident, but i certainly encourage you to think or read about popular history, gentrification, and what it means when the latter tries to erase the former.
As a side note, i don't know about the netherlands, but here in France it's common for neonazis to deface the memorials honoring the (jewish or not, but the jewish in particular) victims of nazism. I agree with you it's bothersome in some sense that jewish victims are honored more than other categories of nazism victims (tsigans, cripples, homosexuals, etc), but if the alternative is to make the neonazis who'd like to rewrite history happy, i'm very happy with the current state of things.
