Did you like the subplot about how slaves who are freed against their will turn to alcoholism? Or how when they celebrated Christmas at Grimmauld place, they put little santa hats and beards on the severed slave heads? Did you like the HIV allegory character who deliberately tries to infect young boys with his disease? What about the constant descriptions of "mannish hands" and general authorial misogyny against women who the reader isn't supposed to like? Did you like how Harry was supposed to be the saviour of magical england from a fascist movement, and yet he's a moderate liberal who never makes an effort to fundamentally change any of the systems of the world, and who wants Hermione to stop campaigning against slavery because it's annoying?
I know you don't like the author (and I don't either, she's a twat), but it's pretty undeniable that literally tens or hundreds of millions of people enjoy Harry Potter.
I don't think they said people don't enjoy Harry Potter. they just said it's bad. and that's correct. jowling kowling rowling is not just a bad person; she's a bad writer.
