I guess the gist of my argument is that if one is seriously into fantasizing about ****, it "might" be a good idea on the part of the individual himself (going with "him," because, lets face it, most would be men) to seek counseling on his own. Just like with heavy metal music, violent video games, violent movies, etc., it's not the fault of the stimuli itself (in this case "**** fantasy porn"), because that was in the indivual who acts out in the first place. I listen to metal at times, I have played violent video games before, and I've seen violent movies too...yet I've never acted out. Why? Because it wasn't in me to begin with, and the stimuli can not plant a seed...it can only help it grow. "**** fantasy porn" is no differnt. I'm not into it at all...but, if I watched anything like that, I would likely be repulsed by it, and it would not turn me into a ******. Like I said, stimuli can not plant the seed....it can only help it grow. If it's not in you, it won't magically become so.
So, like I said, I believe the onus is upon the individual to explore and seek counseling to see why they would fantasize about something as vile as ****. But, in the end it's up to the individual to do, and to want to change. I can only speak for myself, but I know if I started having disturbing fantasizes, I would want to seek counseling and/or treatment before the feelings grew. Societies have their norms...and I'm sure everyone would agree that **** goes against the norms of our society...as it should.
