The vanilla co workers responce however repugnant is all too often the norm. It doesnt surprise me. Bdsm may be more mainstreamed now than ever before, but I am sure its got a long way to go before its fully accepted if ever.
As for the crime and its peurpetrators; I am biased admitabely so, this is my opinion only:
I have zero sympathy for eaither the men involved, both are equally guilty in my eyes the one tricking the other is no excuse for the one doing the act itself, which to commit the monster had to rule out all common sence.
If it were up to me they would both be raped in similar torturous fashion and then fully castrated with a dull knife before being put to death. She may live on, but she will carry her burden forever with her. The least society can do is give her just retribution.
Somthing thats all to many times lacking in our PC world.
