So here we have a paper about *sexism*, garnering a review that is egregiously, over-the-top sexist in nature.
So, this would suggest to me (not by any means an expert) that the reviewer was quite aware of what he was saying -- he was being sarcastic, and/or trying to be funny. In other words, the over-the-top sexist tone was deliberate.
Wise? Probably not. But people often try to make points in misguided ways, and of those, sarcasm probably leads the pack. I'm reminded of the Justine Sacco controversy. Sacco, if you recall, was the flack who tweeted: "Going to Africa. Hope I don't get AIDS. Just Kidding. I'm White!" So all the Right-Thinking People were all outraged. Except, Sacco is a Good Progressive. Her tweet was (obviously, to some of us) an attempt to sarcastically tweak White Privilege. (Picture her saying it while rolling her eyes.)
Same idea might apply here.
