I’ve always thought that pure-blood supremacists should be present in every Hogwarts house to some degree—more in Slytherin, sure, but not *only* there.

Slytherin: No explanation needed. Books covered that.

Ravenclaw: Cooking up pseudoscientific theories (it would be interesting if those theories about Muggle-borns stealing magic—supposedly based on "independent research by the Department of Mysteries"—were actually concocted by a Death Eater from Ravenclaw), plus a ton of data spamming, cherry-picking, straw man arguments, and sophistry.

Gryffindor: "We hate Muggles and Mudbloods because cowardly Muggles killed us in the past; we must protect our magical brothers and sisters from them and not be afraid"—lots of courage and romantic idealism, just channeled in the wrong direction (much like various forms of Nazism and fascism).

Hufflepuff: Probably the least anti-Muggle, but lots of bullshit about how Muggles cause chaos, wage wars, and threaten peace and nature; how children from Muggle families can be maladjusted; and how it’s better to keep everything in the hands of pure-blood wizards—because it’s safer and more stable that way.

I also think it would be interesting to see Death Eaters from other houses—like Gryffindor (no, not Pettigrew), but someone "brave" and loyal in a twisted sense—or to have characters like Barty Crouch Jr. belong to Ravenclaw or Hufflepuff. At the same time, the Order could include decent Slytherins who might personally dislike Muggles but don't view that as a license to harm them—and certainly don't support the genocide of Muggles and Muggle-borns, which an unstable snake-like egomaniac championed as a "super cool" solution(Snape also doesn’t count)

Harry’s perspective makes it look like wizarding racism, rot and bigotry was mostly limited to Death Eaters and their allies, but I really doubt that.

I am re-reading GoDlF and i am on the moment when Hermione literally receives hate mail telling her to “go back where you came from, Muggle” because some random witch or wizard believed she was manipulating Harry. Yes, *that* Harry Potter. The child who banished Voldemort.

I’m sure plenty of older witches and wizards, after three Firewhiskies at Christmas, said something like that to their grandkids:
“Of course You-Know-Who was a bloody monster, and thank Merlin Harry Potter stopped him…what a poor child…but He-Who-Shall-Not-Be-Named did have a point about Muggle-borns. Look how quickly they’re taking over Hogwarts and the Ministry. Soon they’ll take our jobs.”

Basically the wizarding version of my grandma who condemned most infamous Austrian painter and then immediately explain why he was “right about some things and some good came out from it.” 💀

We must have at least two parents who also have two parents (although here... EHMM...there is a certain possibility of "compression" and pedigree collapse already in the second generation of grandparents, if you know what I mean).

My point is, it is literally impossible to NEVER have a Muggle ancestor.

First fully magical generation (2)- sure
second(4) - absolutely possible
third(8), four(16), Fifth (32), sixth(64), - quite possible, and I'm so generous for now because I don't assume (yet? ) inbreeding.

However, we come to the generation 7(128),8(256),9(512) here maybe the Blacks, Gaunts, Lestranges, if they are proud of it, but it seems to be hard to actually take care of it.

10 generation (1024), 11 (2048), the problem begins,
12? Mamma mia (4096)

13 (8192)? chance of a muggle, hidden somewhere in the register seems to be almost certain.

I'm not talking about the fact that the wizarding society in Britain is so small that on some 6-7th generation we have a real decay of the pedigree there, so the maximum of 8192 ancestors on the 13th generation is about 30-40, maybe even 50% fewer ancestors than they should have

Generations 14-17, I don't even want to count, everyone today has a calculator at hand and if they are stubborn, a pencil and a piece of paper will do the job.

My question is - how do they check and count it? Do the Malfoys, for example, because they look like someone who is prudent in such matters, keep books of marriage records and children up to XYZ generations, which show who is with whom how and where and what came out of it?

Or rather, as I understood from the books I recently read and read some information about lore, purebloods marriages are totally "by word of mouth" like "Rosiers, Lestranges, Burkes are pure-blood because they are", and do not investigate the books you filthy mudblood?”

For example, Black Tapestry (from what i know, if i am wrong, correct me! ) contains only... information about Blacks and about people who married to Blacks having children? And where are their ancestors?

I don't mean that I don't catch the obvious hypocrisy that Rowling served us with the mouths of the characters and herself many times. I just mean, how do they in the universe, studying books, analyzing their ancestors, justify it for themselves?
