some would argue that stuff with it would lead others to have fantasies about it and/or do it in real life, and it's better to not know about kinks like that at all, and it could be a slippery slope. others (like me) would say it can be an outlet for those who have those thoughts, and that if they are finding this stuff in the first place they already have these thoughts and know about these things, and it could lead to people doing it if they don't have an outlet for such things, like these things, and as such would help such matters. also it's kinda underestimating the people who watch/play these things, as people can be basically normal people for the most part and still be a part of these things. both sides are intrinsically opposed to the other in their argument, so it's unlikely an agreement can be reached, any time soon, as their perspectives on the matter are complete opposites, and even data might not be enough to convince one side of the facts of the matter.
