As someone who, overall, enjoyed fantastic beasts, it really causes a lot of issues for the worldbuilding
I think fantastic beasts really highlights a flaw in jkrs writing. Mainly, how the rules for her world really only work if you consider white people, and totally fall apart when you consider the same world from anyone else’s point of view.
The idea that in america you can have 0 contact with no-majs is fine, if 1. Everyone is white and/or 2. Magic is entirely hereditary. But neither or those ia true.
The movie takes place, what 60 years after slavery was abolished? What happened when a wizard was born a slave? Were they left to form an obsurial? (No, they say there hadnt been one for centuries in america) were they whisked away to the magical world and expected to leave their relatives to rot in slavery?
The movie takes place 30 years after the wounded knee massacre. What about magical children born in native communities? Are they invited to ilvermony? Do they let their communities be butchered?
What will happen in less than 20 years when japanese internment camps begin? Will witches and wizards of Japanese heritage just pack up and go to the camps too? Will they go into hiding and leave their potentially nonmagical families?
Jk seems content to act as though the Wizarding world has no racsim and instead uses magic vs nomaj tensions as an allegory. But that doesnt work when you have muggle born wizards who would be affected by racism in the nonmagical world.
And i dont think jk has ever even considered this. And it shows.
