I think that's a fair point, for sure. The races thing is a hold over from people who are more used to talking about Starcraft or Warcraft where "race" is a thing that's relevant to talk about unlike a WW 2 game where it can be considered offensive.
Obviously we're all humans, and thus race isn't something that we need to be talking about. We should be saying "faction" instead.
Yet the "Factions" in this game is referenced to as "Races" in the game files, and in the official changelog that you have written you reference the "Factions" as "Races"
