I knew someone was going to say that. Here is the way I look at it. Anything that is taboo or fetish in our society is a slippery slope. Once your step over your moral boundary once, that becomes your new boundary. Then you step over that moral boundary again, and have a new one. Until your at the point where your far beyond what your previous moral expectations would have put you. I learned this from smoking weed. At first I told myself I would never ever smoke it. Then I tried it once, and a year later and I was a pothead, its the natural progression.
