Query: Bigoted and disempowering

I find serious scientific problems with this book, and moreover the authors aggressive disenfranchisement of BDSM. Her framing of masochism is encapsulated in the legacy of antiquated theory, with seemingly no appreciation for the empancipatory science that created mental health reform around gay/lesbian identity. There is a lot written, both before and after, that offer a much more balanced and empowering view of BDSM. Her closing paragraph borders on sexual harassment...she reads like a bitter second wave feminist, too rigid to share diverse sexual voice and join the third wave. Not recommended, other than as an example of the stigma that still exists against BDSM within academia.
