The fact that certain characters are inherently just evil underlines how childish the books were. The author wrote these stereotypical villains as coded as marginalized groups (fat, racialized or queer) and a generation enthusiastically nodded along. Don't push against the natural order because slaves enjoy being slaves. The heroes are always heroes because even if they do the literal same exact actions as the villains, they aren't overweight so it's for hypocritically described as heroic.

Here you are citing this bigoted text to claim others are categorically crappy people, which only demonstrates your uncritical acceptance of those biases as "fact" and anyone who disagrees with you as inherently a lesser form of person.

My controversial take is Potterheads will ignore the real life explicit bigotry of the author so they can continue to cite her bigoted fiction as bigoted fact. You're all far too old to be talking this childishly.
