The thing is, we know what the Death Eaters are like in the books, and they don’t even resemble JKR’s paranoid, bigoted idea of evil trans conspiracy.
The DEs are the wizarding world’s equivalent of neo-Nazi thugs, Britain / America First xenophobes, and privileged people resentful of the society no longer keeping their “lessers” down or allowing casual, callous violence towards them. They are a reactionary backlash to increasing equality, shaped into a cult of personality by a charismatic sociopath.
In other words, they are exactly TERFs like Rowling herself and the far-right bastards they’ve joined forces with. She’s projecting madly, and she’s even failing at that, because all the hate has made her stupid to the point where she no longer even understands her own books.
