@londubh So, one of the women mentions an incident that only happened in her head (she could “practically smell the silent impatience from the men nearby”) and in a different field (geology), and that is somehow proof of sexism in astronomy? And the fact that she now leads a NASA mission doesn't serve as counterexample?
And what about the other women featured, who fail to provide a single concrete fact to back up their claims?
I mean, didn't the authors know about Jocelyn Bell, who discovered pulsars and was robbed of a Nobel prize by Antony Hewish? Now that's a blatant case of sexism in science in general and astronomy in particular! But I bet she doesn't appear in any of the books they're clearly advertising.
if this guy, and this guy's website, are parroting them around as if it was credible scholarship then you already know that no honest reason will convince him to change his mind
