I'm surprised you found that rebuttal strong, I found it exceedingly weak. She complains that the original author used a few of her own unreviewed studies, fair criticism, but doesn't present any evidence that it was wrong. She complains that the original author painted the research as one-sided that men negotiate better, then reviews the research and show that it is in fact pretty one-sided. Then, having done nothing to really dispute the accuracy of the research evidence being presented, she goes into an unsubstantiated rant about privilege and minorities, which is largely unrelated to the book. It's true maybe the original book failed to address some of these issues, but it doesn't make the book wrong as much as incomplete. As she completely fails to hide her overarching political bias going into the rebuttal, her rebuttal made no striking critique on the book's research nor presents much conflicting research, and half the rebuttal was spent rehashing third wave feminism talking points rather than making scientific arguments, only to summarize by saying that book was shoddy science and sexist, I would not consider this a strong rebuttal at all.
