The whole Voldemort/Death Eater/pureblood movement is clearly an allegory for white nationalism.

They believe themselves to be superior and more pure. They look down on people not like them, and they view wizards who intermingle with muggles to be race traitors.

The tone of the books is pretty “woke”, so it’s crazy to me that JKR is now liking and retweeting statements from nationalists and the far right.

They really found common ground on the whole trans people being subhuman thing.
