Do you crossboarders have no knowledge of history? Of course if you just see "40 million died in the Cultural Revolution" or "There were 27 million Soviet casualties in World War II" in a history book it doesn't matter because you have no frame of reference for those people. But if you actually show those people, get any context on who they were, their situation, or how they specifically died, it's plenty easy to feel empathy. Compare "Unit 731 is estimated to have killed 200 thousand people" to "Unit 731 engaged in lethal human experimentation including removing organs, injecting chloera, amputating and resewing limbs, and forced sex acts to spread syphilis, which resulted in the deaths of 200 thousand people". Do burgers not remember the Vietnam War or did seeing people die of napalm just traumatize them into blocking out anything that could be a reminder?
