i think people need to realize that hetalia focuses more on random bits of history here and there that are generally looked over by books. not to mention hetalia portrays nations in a humorous manner, like in a way that makes you realize, “hey, people in other countries are people too.” yanno what i mean? it’s not about the war itself, it’s about the things that happened during it, the relationships, the people that went through it.
how many of your history classes went over the dandelion coffee thing, for example? it’s something silly, but it was still a great achievement for the people who discovered it! hetalia focuses more on the human parts of nations rather that the governmental moves of it, i guess, is what im trying to say here.
not that it doesn’t touch upon battles, though, because it clearly does. i just don’t see how hetalia, a humorous, almost slice-of-life (or earth rather) anime/manga can handle something like the holocaust, and i don’t see why it needs to. you can respect something by choosing not to adapt it as well, and i honestly think it’s a good thing we don’t bring it up in canon.
and that whole “the axis powers did nothing” argument is such bullshit like both sides of the war did terrible things IN ANY WAR WE’VE HAD??? yet the allies are treated just like the axis and no one gripes about them.
same goes for older wars. nations are comprised of people, and that’s the part hima chooses to represent. anyone would be pissed to see their country portrayed in an evil and demeaning fashion????
