Although I will come to the defense of gender studies against the sorriest excuse for a hoax I have ever seen, I don’t like gender studies that much. I would never claim that the whole field is pathological–that is not in evidence. But I have read some gender studies papers, and have not been generally impressed with them.
Yes, I have, as a physicist, read gender studies papers. And I didn’t select papers by following right-wing news sources that intentionally cherry-pick the most ridiculous examples. No, I read gender studies papers as part of my work as an asexuality activist. Back in the day, my other blog hosted a journal club on academic asexual studies. Asexual studies are very cross-disciplinary, including psychology, sociology, history, linguistics, law, and… gender studies!
The short version: Gender studies papers often say stuff that activists already know, or already know is wrong. I am not sure what advantage gender studies provides over, say, blogs.
