This post disturbs me because I have seen many subs left in severe emotional distress after being almost brainwashed into believing they are really worthless before being dumped by their master and left all alone with their self esteem in tatters. A lengthy rebuilding process is then needed to get them out of their doldrums and back on their feet. I understand and enjoy humiliation as a bdsm activity but, just as with physical activities, great care needs to be taken so as not to leave any permanent (mental) scars.
Lilly27 got it spot on, what does it say about the masters that they own a worthless piece of shit. I wonder if their cars or computers are also pieces of shit.
