This sort of gender-specific walled garden is nothing new and I suppose will always attract a certain stereotype. Here's an old Anthony Lewis post from 1994 that may sober folks on the idea: http://www.nytimes.com/1994/10/14/opinion/abroad-at-home-tim...
"I wouldn't want to belong to a club that would have me as a member" --Groucho Marx
Call an obnoxious speaker a jerk: what a useful formula, what an intelligent way to get the resentment off your chest without starting down the legal road to suppression of speech. It would have worked well, for example, in the notorious case of Prof. J. Donald Silva of the University of New Hampshire.
I find this section to be a disturbing summation of the author's attitude on the subject. And, the Groucho Marx quote has no bearing on any of this; it's self-deprecation.
