I found this email politely amusing:

Dear Jonah,
I find your “review” of Kate’s book at least a little ironic. Why were
women’s colleges established at all, you never bothered to ask.
Perhaps it was because all-male universities did not want to admit
women, or had quotas for them, like they had for jews like you and me.
Or perhaps it was because society in general believed that women need
to study different subjects, like art and literature, not biology or
engineering. It was indeed feminism that forced your college to become
gender-integrated — it was feminism that allowed you to be in the
very socially advantageous position of being one male for every 30
female students. And of course it was feminism that let you date
around in this pool of single women; these women would not have given
you the time of day if you had tried to date them in the 50’s, and
certainly would not have slept with you, save for feminism.
And of course, it was feminism, and not anti-feminism, that forced
people to respect the opinions of women like your wife and Kate, and
not to simply dismiss them because of their genders. It’s nice to see
that you don’t completely vilify feminism, and admit that it has made
life better women, but i also have disagree with your idea (that you
don’t even back up) that “those battles were won a long time ago.”
Feminism began to sprout 50 years ago, and societal changes started to
happen in the 60’s and 70’s, which is hardly a long time ago.
I wish you and Kate would do more research and back up your
categorical conclusions with something other than your own ideologies.
