I counted books that seemed to have sadomasochistic themes by no less than 7 authors at Target the other day, many of whom had 3-4 books. To be clear, as I understand the matter, these books deal with men who like to tie their women up and stick butt plugs in them, who are emotionally both dangerous and shallow. The success of 50 Shades of Grey has inspired many imitators, or driven up sales of similar work.
It is difficult sometimes to be sanguine about the future of our culture. Still, one never knows what may make a difference, and our field of endeavor is our lifespan.
