English publisher tells kids Joan of Arc was transexual

In an anthology entitled Who We Are, published by Collins and aimed at teenagers aged 11 to 14, Joan of Arc (Jeanne d’Arc) is presented as a non-binary icon for the edification of schoolchildren. We had to wait until the twenty-first century to finally get to the bottom of the story. Holy cow, of course! Jeanne is non-binary. Why didn’t we think of it sooner?
