I love the contrary dame (not a Dame!) and I don't care if she isn't a proper feminist. She was raising the hackles of proper society when she wrote The Female Eunuch and now she's raising hackles of proper feminists (of all genders) by disagreeing with some feminist cast-iron rules and tropes.
Bravo brava Germaine! Long may you continue to challenge the status quo, whenever and wherever it calcifies. As soon as any movement becomes established as an "ism", it seems inevitably to calcify into institutional and intolerant positions it initially battled against. It's as if the vitality of a flowing river freezes into an icy pond - fine to skate on but don't dare to crack holes in it!
Sorry I linked to the Telegraph article below without realising they won't let you read it all without paying!
