This gets back to the entire debate we've had ad nauseum about whether or not the only purpose of sexual activity/intercourse is for procreation.
Some people believe this to be the case - - others have different ideas about this. If you're of the belief that procreation is a byproduct of sexual intercourse, rather than the primary goal, then that might change your point of view.
I do not argue that there are multiple results and purposes of intercourse, that is the nature of it for human beings. I do think of it in terms kind of like the choice to carry a firearm (concealed carry). The purpose may be for protection or recreation, but the outcomes can be far different, and anyone who does carry a firearm, regardless of their intent, are responsible for any outcomes that may occur. Just because they didn't mean to hit a bystander does not mean they are not liable for it.
I think the same goes for sexual activity. Sure it is completely legitimate to be use for recreation, but that does not absolve one of the responsibility for the outcome. If you engage in an activity that by its very nature can have a (perceived) negatvie outcome, you need to be prepared to deal with that outcome, whatever it may be. Be it disease, emotional scarring, or a baby, if you engage in recreational sexual activity as many of us do, you need to be prepared to deal with the consequences.
Unfortunately things like the lady who sued McDonald's over hot coffee and won have changed how we view personal accountability. She should have known that putting a flimsy cup of very hot liquid between your legs while driving could potentially have a negative outcome, and she should have accepted responsibility for the outcome. Instead she gets rewarded for stupidity and she is in no way held accountable for the choice that caused the issue to begin with.
I know there are many many layers to this debate, but for me the core of it is that we are intelligent beings that should have some understanding of choice and consequence. If you do not want, or will not accept responsibility for a potential outcome to a behavior, then you should not engage in that behavior. To me that is the core of being a productive member of a society.
As well as what separates intelligent people from the dumbasses out there. =)
