Rowling herself for comparing people who fall for fake news (that's everyone, at some point) to unwitting collaborators of totalitarianism...
I think the point she was
trying to make - on fucking
twitter, jfc - isn't about people
falling for fake news, but about the people who just stop
caring about truth point blank and start believing in
symbols, which is indeed one of the routes to totalitarianism and why you get those mythic imageries of dictators all over a dictatorship, to abstract away the actual truth of the man into the symbol of the regime
