How is it a plot hole? Her exact line is “Perhaps the most significant effect of Salem was the creation of the Magical Congress of the United States of America in 1693, pre-dating the No-Maj version by around a century.” She directly states how it predates the creation of the USA further she talks to the rather loose…

And who’s to say that he didn’t get it from his friend Joe the Wizard? I think the implication of the text was that the No-Maj were aping the Wizarding Communities innovations (either by influence or inspiration from the Wizarding community).

I figured it was one of those things where the magic subtly influenced the world around it so that is how our Congress got the name etc.

Neither do I. If she had left Native Americans out people would be complaining about that instead. I guess the internet was having a boring friday and needed something to be offended about.

“As someone completely removed from the context of the issue, I see nothing wrong with it.”

Says who? Rowling has no more obligation to American or British real history than the White Wolf RPG designers had, or the guy who wrote about Lincoln being a Vampire Hunter, or Harry Turtledove. IT IS FICTION!

At least this article is filed appropriately. It starts out re-iterating already-discussed problems with J.K. Rowlings generalizations of Native Americans, lumping them all up as a single group, etc, etc.
