I've just read the excellent introductory essay:
In the late 1990s and early 2000s, many Christians saw her stories of witchcraft as dangerous for children, both sinful and poisonous. They made films and wrote books decrying her influence, sermonized against her, and campaigned to have her work removed from schools and libraries. Their efforts to censor the series made “Harry Potter” among the most banned books of two different decades. Some of these Christians, too, burned her books.
And yet it's the GC feminists here who get accused of "aligning with the bigoted Christian right"...!
