I don't think that's entirely true, I know at least one woman IRL who's gotten into it a bit and even converted to christianity and shit, and even if it's not really taking off wildly, it does present a challenge that liberal, choice-focused (rather than liberation focused) feminism doesn't have great responses to, namely "what if I freely choose a traditional, even subservient role?"
anyhow I'm sure theres an ebook of it around somewhere I'd love to hear criticism of the book tbh, I just read it late last year
