Also, the whole house elf thing was… Really, really rough to read as a kid. I could never understand why no one was on Hermione’s side, and how no one could see that elves didn’t want to be free because their condition would be that of an outcast, and in a world where only wizard’s were allowed wands, nonhuman humanoids were veru clearly subjugated to the point of delusionality.

The motivation behind the idea was a good one, the execution of the idea was absolute cringe.

Let me explain. The intention was to highlight that the wizarding world has its own logic, and trying to apply the morality and philosophy of the mundane will end in failure, but Hermonie can't see that being too smart for her own good in this area...

Unfortunately JK picked FUCKING SLAVERY as the way to make this point, because she is a dumbass. No, that's underselling it: She's a fascist who only had Voldemort be evil because the book needed a villain. JK Rowling legitimately believes that some groups of people are perpetually below "The normals"

Like take the concept of Royalty (Some people are better than others because they are of Noble Blood) and turn it onto its head, that there are people who are lesser than others because they are of dirty blood. (To JK these include the Irish, transgender people, and anyone who isn't white)

"Mudblood" being a slur in the HP Universe is just JK's way of projecting her worldview onto perceived enemies.

Oh and one last thing. JK did the "Wizard morality is different because it's wacky and whimsical" a second time, in the Fantastic Beasts movies, where the worst crime in Wizard History was.... drumroll Trying to stop the Nazis from coming into power... (You see why Harry Potter just doesn't work with serious stories?: JK herself is impossible to take seriously, and infact is outright dangerous because there are those who attempt to do just that.)
