The Harry Potter fandom Wiki includes "blood status" as the second element on a character's "biographical information".

It's giving "wizard Nazi".

I get why within this story-world "blood status" is occasionally relevant: bigotry & targeted violence are often based on someone's "blood status" (or perceived status), but to list it as part of basic biographical information is to legitimize it in a weird way.

(I searched a character from the Harry Potter play out of vague plot curiosity).
