If they're a reader of fanfiction that is typically one of the major changes to the story that's done. Fanfiction has effectively rewritten the entire series to be more palatable at this point. Bonus points that you can read it without giving Rowling any money too.

None of that is correct.

• The slave thing was about brainwashing and exploitation, and how it's wrong.
• I don't know what you're referring to with the apartheid thing.
• The goblins are antisemitic because they have big noses? That's been a staple of goblin anatomy since they were created.
• The main character becomes an anti dark sorcerer guy, like counterterrorism, so nothing to do with enforcing all that gubbins anyway.

Oh, and thanks for the '/s'. You know, otherwise I really would've thought you were giving it a compliment after a full paragraph of invective.

apartheid is right because the other sentient people look different

This is what the fucking bad guys believe, it's not like the books are advocating for apartheid. What the hell kind of criticism is this.
