We read the book Inferior for book club and had a very good discussion around it.  The book had some pretty major holes and obviously had an agenda.  The history part of the book was probably the most well done part, and the part the book was truly trying to describe well.  I think the science for the final argument the author was trying to make was a bit lacking, but a major point in the book is that lack of evidence is a major problem in the field of gender studies.  There is also the nature vs. nurture problem, which was covered a little as well.  We got into a lot more personal impacts than we had with previous books, and the discussion format I think helped with that.  The sunflower conch allows for people to take the time to really compose their thoughts and express things that would be steamrolled otherwise.
