About All of 'There were no women in the Great War' Responses to Anime Artwork

Just to get this out of the way, I hate anime. I really HATE anime. But the whole 'historical accuracy' argument is just stupid, or at least it is with this game. There were women in WW1, the Russians had the Battalion of Death, a specific all-female regiment, and some women did pretend to be men, enlist and sometimes even get to the front, so complaining about the presence of women is ridiculous when this game has weapons (looking at you, Helligrel) that never came into service being used on mass.
Sexualization isn't good, but don't use the historical accuracy argument. It doesn't make sense.
