Body Type 1, Body Type 2 is retarded as fuck. If they made it male/female, and you were transgendered -- well, you get to be whatever the fuck you identify as. What the hell is Body Type 1 and 2 for? Non-binaries? Gender fluids? That's faker than magic.

iirc only Dean Thomas, Angelina Johnson, and Cho Chang are the only nonwhite students that get a mention in the books

There was a Patel something too. Which actually made sense since there is a significant Indian minority in England, having been their colony for hundreds of years.

That said, it made sense for a British school in the 2000's. There would probably be one or no minorities from England's colonies at a prestigious school in the 1890s. And any that were there, would primarily be a token to show how magnanimous their British masters are in civilizing the lower races. White Man's Burden and all that, old chap. I doubt that's a subplot this game would like to explore.

.......and then there's accidentally implying that a genocide will happen that wipes out nearly all the POC to account for why so few exist a century later.

Voldemort?

Voldemort killed all the minorities because he is Mega Giga Hitler
